In lipid A produced with sodium acetate buffer (0.1m NaOAc, pH4.5, 1h, 100C) the degree of Etn-P substitution at position 4 (73%, w/w) is slightly lower, whereas substitution at C-1 is decreased to one half (45%, w/w) compared with native LPS (80%, w/w). W. H. Freeman and Company, New York. To learn more, see our tips on writing great answers. The presence of excess phosphates in freshwaters reduces the amount of oxygen available for the survival of the aquatic animals. In order to measure the enhancement in stability due to LDH interaction, IAA, IAA-LDH, and IAA-ZBS were dispersed in water and their concentrations were monitored for 10days. Phosphate Group The last part of nucleotide structure, the phosphate group, is probably familiar from another important molecule ATP. 6.8 [99,100]. We have recently reported the intercalation of folic acid and its derivatives into LDHs for use as a drug stabilization and delivery system.31 Folic acid (N-(4-{[(2-amino-4-oxo-1,4-dihydropteridin-6-yl)methyl]amino}benzoyl)-l-glutamic acid) and its derivative, folinic acid ((S)-2-[4-[(2-amino-5-formyl-4-oxo-5,6,7,8-tetrahydro-1H-pteridin-6-yl)methylamino] benzoyl]aminopentanedioic acid) are used in cancer therapy and in the treatment of vitamin deficiencies. General structure of nucleosides and nucleotides is illustrated in Fig. Part of figure 25-5. Lehninger 5th edition. This complex helps stabilize the DNAwhich as important in several ways Browse other questions tagged, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site. As the sole member of the head group, the phosphate imparts a -2 charge to the lipid molecule and is referred to as phosphatidic acid (PA). WebThe phosphate group attached to the 5' carbon of the sugar on one nucleotide forms an ester bond with the free hydroxyl on the 3' carbon of the next nucleotide. This is generally true of freshwater environments, whereas nitrogen is more often the limiting nutrient in marine (seawater) environments. Ribose vs. Deoxyribose | Structure & Function. Uptake of these substances by plants and marine life can lead to concentration of toxic heavy metals in food products.[21]. The electrons in these bonds are high energy, meaning that when the bond is broken, plenty of energy can be released to do work. Drug molecules and other biofunctional molecules require stabilization because they can easily be destroyed or expelled by various drug-resistant mechanisms in biological systems. If it is assumed that the phosphate minerals in phosphate rock are mainly hydroxyapatite and fluoroapatite, phosphate minerals contain roughly 18.5% phosphorus by weight. The presence of a negative charge causes phosphates to act as a nucleophile; it seeks a positive charge, therefore it is always found bound to other atoms or molecules. Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. (a) X-ray diffraction patterns for various vitamins intercalated in LDH and (b) corresponding structures. Profiles of UV absorbance for (a) DNA and (b) DNA-LDH hybrid treated with DNase I as a function of time. Cytosine (C) and Thymine (T) are smaller pyrimidines with a single ring structure. (6) In a completely different role, exposure of PS to the extracellular side of a membrane is often a cellular marker for apoptosis, or programmed cell death. CLA alone, stored in a 50C chamber, completely decomposed in 7days, while intercalated CLA exhibited long term thermal stability, for 49days at 50C. Some phosphate rock deposits, such as Mulberry in Florida,[13] are notable for their inclusion of significant quantities of radioactive uranium isotopes. What part in the strand contributes to the overall non neutral charge? Hydroxyl Group | Structure, Formula & Examples. For a small, spherical particles, the balance of electric and viscous forces results in an electrophoretic mobility (u, defined as the particle velocity per applied electric field strength) given by. 2005. WebIn a cell, a nucleotide about to be added to the end of a polynucleotide chain will bear a series of three phosphate groups. The four oxygen atoms in the phosphate groups are linked to the phosphorus atom forming a tetrahedral geometry. phosphoric acid .mw-parser-output .template-chem2-su{display:inline-block;font-size:80%;line-height:1;vertical-align:-0.35em}.mw-parser-output .template-chem2-su>span{display:block;text-align:left}.mw-parser-output sub.template-chem2-sub{font-size:80%;vertical-align:-0.35em}.mw-parser-output sup.template-chem2-sup{font-size:80%;vertical-align:0.65em}H3PO4. Given that the thickness of a brucite-like LDH sheet is 4.8, the gallery heights are estimated to be 17.1, 14.3, and 15.1 for folic acid-, folinic acid- and MTX-LDH intercalates, respectively. Was: $165.00. Can we create two different filesystems on a single partition? There are 3 hydrogens in phosphoric acid, each of them leaves as: 1 H joins with 3' -OH of previous nucleotide to form $\ce{H2O}$ during DNA replication. The phosphate group is a chemical structure that consists of one phosphorus and four oxygen atoms. "Molecular properties of various structurally defined sphingomyelins correlation of structure with function". Enrolling in a course lets you earn progress by passing quizzes and exams. As a rule, the hydrogen and dihydrogen phosphates are slightly more soluble than the corresponding phosphates. As cibrail said, DNA is a polymer of nucleotides. Secoiridoids are a diffused group characterized by the cleavage of the 7,8-bond on cyclopentane ring (Fig. As cibrail said, DNA is a polymer of nucleotides. They join themselves through phosphodiester bonds (a specific kind of covalent bond) that can gro One of these oxygen atoms is attached to the glycerol backbone. A DFT investigation Charges of phosphate groups. The DNA molecules are VERY long and easily broken AMP, ADP, and ATP) and in DNA and RNA. It is, however, an indirect method for the detection of phosphopeptides and a more detailed analysis of the native phosphopeptides by MS/MS is required to localize the exact phosphorylation sites. The largest global producer and exporter of phosphates is Morocco. PC's other major role is as an integral component of plasma lipoproteins, where it accounts for 60-80 mol% of total phospholipids. Free amine groups as present in phosphatidylserine or phosphatidylethanolamine show a single sharp absorption band at 1075cml. In biological systems, phosphorus can be found as free phosphate anions in solution (inorganic phosphate) or bound to organic molecules as various organophosphates. Generally, hydrogen is not shown in DNA structure. As a member, you'll also get unlimited access to over 88,000 [9] Phosphorus comprises 0.1% by mass of the average rock[10] (while, for perspective, its typical concentration in vegetation is 0.03% to 0.2%),[11] and consequently there are quadrillions of tons of phosphorus in Earth's 31019-ton crust,[12] albeit at predominantly lower concentration than the deposits counted as reserves, which are inventoried and cheaper to extract. For example, as part of the metabolism of glucose the hydroxyl group at C-6 is phosphorylated in a reaction with ATP to give glucose 6-phosphate and ADP. Attach that cluster to one of the many carbon-containing molecules in our bodies (or, really, in any living thing), and we call that group of one phosphorus and four oxygen atoms a phosphate group. From: Encyclopedia of Biological Chemistry, 2004, Mads Grnborg, Ole Nrregaard Jensen, in Journal of Chromatography Library, 2003. Phosphate groups turn up in all kinds of important places. From a chemical point of view, iridoids are atypical monoterpenoids; as basic structure, in general they can be described as methylcyclopentane-[C]-pyran, in which a methylcyclopentane is fused to a six member oxygenated ring, forming a bicycle system with 10, 9, or rarely 8 carbon atoms (Fig. For instance, essential fatty acids, such as conjugated linoleic acid (CLA) and -linolenic acid (GLA), and flavor molecules such as vanillic acid (VA) have been successfully introduced into layered materials. The biosynthesis of iridoids consists of two pathways, in which secoiridoids and iridoids are in carboxylated and decarboxylated form; they are called pathway I and II. Two phosphate groups combine to form an inorganic pyrophosphate with the bond called as phosphate anhydride. The result is a free-floating phosphate plus ADP, or adenosine diphosphate (meaning it only has two phosphate groups). Where would ATP be without its phosphates? In agreement ESR experiments show no evidence for phosphate ionization in DNA after gamma irradiation [10, 101]. Phosphate groups are common in nucleic acids and on phospholipids (the term DNA is not isolated in the body, so what keeps it stable while being charged? There exist a variety of phospholipids with varying head groups and hydrocarbon tails. So, in a chain of DNA or RNA, each nucleotide has just one phosphate group. As a result, nucleic acids migrate readily in an electric field from the cathodic to anodic (negatively to positively charged) ends of the apparatus. Around pH 9.8 (mid-way between the second and third pKa values) the monohydrogen phosphate ion, [HPO4]2, is the only species present. Thus, the DNA strands require 34 2 of area per single negative charge. At pH 1 or lower, the phosphoric acid is practically undissociated. A total of 16 carbon atoms are contained in palmitic acid. Extraction and isolation methods from plant organisms is well known for a good number of iridoid glycosides. Each nucleotide comprises of three components such as a phosphate group, a nitrogenous base, and a deoxyribose. The Distribution and Function of Phosphatidylserine in Cellular Membranes". Following dephosphorylation, complete inactivation of the enzyme is essential if the subsequent ligation reaction is to work efficiently. The phosphate moiety Phosphates are used for the activation of proteins to make them perform specific functions. The discovery of the structure and functions of nucleic acids enabled a development of molecular biology for their multiple functions. Yang et al.63 have recently demonstrated the intercalation of indole-3-acetic acid (IAA) into ZnAl-LDH and ZBS for safe preservation and controlled release. (4256). These values are smaller than the longitudinal molecular dimensions of folic acid (19.7), folinic acid (21.5), and MTX (21.2).

Try refreshing the page, or contact customer support. Proteins are activated by a phosphate group so that they can perform specific functions in the cells. Why is it important for DNA to be charged? In water solution, orthophosphoric acid and its three derived anions coexist according to the dissociation and recombination equilibria below[3]. Great answer! This is an amide group, a very stable acyl functional group. Figure 3. Adenosine triphosphate, or ATP, is the energy molecule that most life on Earth relies upon Phosphorylation of protein happens in all life forms. This indicates that the pyrophosphate group of Etn-PP at C-4 is resistant to mild acid hydrolysis, whereas that of the -glycosylically linked Etn-PP group at C-1 is susceptible to even mild acid hydrolysis. All other trademarks and copyrights are the property of their respective owners. At high enough concentrations, fatty acids will aggregate to form spherical structures called micelles, which are energetically favorable structures that increase the entropy of water by minimizing water clathrate formation around the hydrophobic regions. Carboxyl Group Structure & Examples | What is a Carboxyl Group? Nucleotide monophosphates such as adenosine-5-monophosphate (AMP), guanosine-5-monophosphate (GMP), and cytidine-5-monophosphate (CMP) and also deoxyribonucleotides (Herring testis DNA 1002000 base pairs in length) have been successfully intercalated into MgAl-LDHs via ion-exchange reactions.15,17,41 Figure 2 shows schematic illustration of the interlayer orientation of DNA strands that have been intercalated into LDH and their circular dichroism (CD) spectra, which indicate that the anionic DNA strands are tightly bound to the positively charged LDH layers, thus forming stable structures. One group of these derivatives is composed of salts containing the phosphate ion (PO43), the hydrogen phosphate ion (HPO42), or the dihydrogen phosphate ion (H2PO4), and positively charged ions such as those of sodium or calcium; a second group is WebRevolutionary, reliable green energy, were Battle Born Batteries. The three phosphate groups, in order of closest to furthest from the ribose sugar, are labeled alpha, beta, and gamma. Over 2500 iridoids are described in nature, which differ mainly for the type and degree of substitution on the cyclopentane ring [98]. Area demand per unit charge of DNA molecule: therefore area per unit charge=3.4/1bp20/2e=342/e. [19], Calcium hydroxyapatite and calcite precipitates can be found around bacteria in alluvial topsoil. We use cookies to help provide and enhance our service and tailor content and ads. By convention, they are usually drawn in their fully deprotonated states. High phosphorus is linked to cardiovascular mortality in chronic kidney disease before and after the beginning of renal replacement therapy. A partial loss of phosphate (HPO3, 80Da) is seen in MALDI reflector TOF MS in the case of tyrosine phosphorylated peptides [30,36]. This is the ester functional group. The tails can also contain carbon ring structures, hydroxyl groups, and additional methyl group branches (Figure $\PageIndex{1}$). The major factor influencing properties such as melting point and water solubility is the ordering of water molecules around the hydrophobic tails. Thanks to the fact that it is negatively charged, it becomes spontaneously pretty straight when denaturalised, because negative charges repel themselves. Hydroxyl Group: Definition, Structure & Formula. Because of the unique ionization properties of its head-group, which can deprotonate to a -2 charge in the process of forming an intermolecular hydrogen bond, it serves a crucial role in the binding of basic protein and small molecule compounds (2). Hydrolysis of diloxanide furanoate in the body is required for it to be effective against intestinal amebiasis. Other electrophoretic parameters, such as applied field strength and temperature, have an effect on the mobility of the different chain length nucleic acids and on the separation efficiency. Many CG models have been proposed over the years, for example, see refs. DNA: Chemical Structure of Nucleic Acids & Phosphodiester Bonds. Plus, get practice tests, quizzes, and personalized coaching to help you The phospholipids are amphiphilic. The hydrophilic end usually contains a negatively charged phosphate group, and the hydrophobic end usually consists of two "tails" that are long fatty acid residues. Unlike the micelle, the liposome has a bilayer wall enclosing a hollow, aqueous cavity, and is used organisms as a transport mechanism for any number of substances. The best answers are voted up and rise to the top, Not the answer you're looking for? If these bonds are broken, energy is released. (2012). Get unlimited access to over 88,000 lessons. Sci-fi episode where children were actually adults. The Ca2+ and Mg2+ ions may neutralize intermolecularly negative charges of lipid A. From the biosynthetic point of view, iridoids derive from isoprene units which are formed in the mevalonic acid (MVA) pathway (in the cytosol), which in turn derived from 2-methyl-d-erythritol 4-phosphate (MEP) pathway in plant plastids [104106]. BAP is more active than CIP and as a result is much more resistant to heat and detergent inactivation. Which transport mechanism Show transcribed image text Expert Answer 1st step All steps Final answer Step 1/2 As per the Chegg guidlines we will solve the first question for you. This sheet is so stable that it's what our cells are made of! The protein function is regulated by the enzymes which add or remove a phosphate group from the side chains of serine, tyrosine, or threonine residues. It is noteworthy that most of the substituents on the phosphate, such as Etn, l-Arap4N, and GlcpN carry, at neutral pH, a positively charged amino group. { "1.01:_Charged_Lipids" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "1.02:_Lipid_Headgroup_Types" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "1.03:_Lipid_Tails_and_Saturation" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "1.04:_Glycolipids" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "1.05:_Sphingolipids" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "1.06:_Sterols_and_Sterol_Induced_Phases" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "1.07:_Lipids_in_Non-Aqueous_Environments" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()" }, { "00:_Front_Matter" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "01:_Lipids" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "02:_Membranes_-_Aggregated_Lipids" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "03:_Membrane_Phases_and_Morphologies" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "04:_Membrane-Protein_Interactions" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "05:_Experimental_Characterization_-_Spectroscopy_and_Microscopy" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "06:_Experimental_Characterization_-_Mass_Spectrometry_and_Atomic_Force_Microscopy" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "07:_Computational_Characterization_of_Membranes" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "zz:_Back_Matter" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()" }, [ "article:topic", "fatty acids", "Phospholipids", "Phosphatidic acid", "Sphingomyelin", "Phosphatidylethanolamine", "Phosphatidylinositol", "license:ccby", "showtoc:no", "licenseversion:40", "source@https://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-013-electromagnetics-and-applications-spring-2009" ], https://phys.libretexts.org/@app/auth/3/login?returnto=https%3A%2F%2Fphys.libretexts.org%2FCourses%2FUniversity_of_California_Davis%2FUCD%253A_Biophysics_241_-_Membrane_Biology%2F01%253A_Lipids%2F1.01%253A_Charged_Lipids, $ \newcommand{\vecs}[1]{\overset { \scriptstyle \rightharpoonup} {\mathbf{#1}}}$ $ \newcommand{\vecd}[1]{\overset{-\!-\!\rightharpoonup}{\vphantom{a}\smash{#1}}} $$\newcommand{\id}{\mathrm{id}}$ $ \newcommand{\Span}{\mathrm{span}}$ $ \newcommand{\kernel}{\mathrm{null}\,}$ $ \newcommand{\range}{\mathrm{range}\,}$ $ \newcommand{\RealPart}{\mathrm{Re}}$ $ \newcommand{\ImaginaryPart}{\mathrm{Im}}$ $ \newcommand{\Argument}{\mathrm{Arg}}$ $ \newcommand{\norm}[1]{\| #1 \|}$ $ \newcommand{\inner}[2]{\langle #1, #2 \rangle}$ $ \newcommand{\Span}{\mathrm{span}}$ $\newcommand{\id}{\mathrm{id}}$ $ \newcommand{\Span}{\mathrm{span}}$ $ \newcommand{\kernel}{\mathrm{null}\,}$ $ \newcommand{\range}{\mathrm{range}\,}$ $ \newcommand{\RealPart}{\mathrm{Re}}$ $ \newcommand{\ImaginaryPart}{\mathrm{Im}}$ $ \newcommand{\Argument}{\mathrm{Arg}}$ $ \newcommand{\norm}[1]{\| #1 \|}$ $ \newcommand{\inner}[2]{\langle #1, #2 \rangle}$ $ \newcommand{\Span}{\mathrm{span}}$$\newcommand{\AA}{\unicode[.8,0]{x212B}}$, Biochimica et Biophysica Acta (BBA) - Molecular and Cell Biology of Lipids. With increasing degrees of unsaturation in the tails (increased number of double bonds), the effect is reversed. Nucleoside analogues represent the basic structures of various important therapies, including antiviral and anticancer treatments [159]. Nitrogenous Bases in DNA & RNA | What is a Nitrogen Base Pair? Quaternary amines such as phosphatidylcholine or sphingomyelin have a doublet at 1087 and 1053cm1 and a sharp band at 961cml. Choi, in Comprehensive Biomaterials, 2011. And of course, histones wouldn't be able to join DNA and exert their key regulating functions. Being a natural resource, this metabolite is enantiomerically pure, defined chiral template because it is synthesized by biosynthetic pathway employing enzymes. As shown in Figure 6(a), over 10days, the active concentration of the free IAA molecules decreased gradually to 40% of the initial concentration. How to check if an SSM2220 IC is authentic and not fake? Plants take up phosphorus through several pathways: the arbuscular mycorrhizal pathway and the direct uptake pathway. Structural differences in the interlayer orientation result from the different charge densities of the ZBS and ZnAl-LDH (5.8e/1002 and 5.0e/1002 for ZBS and LDH, respectively).63 Consequently, ZBS can contain more IAA molecules per unit charge than LDH, resulting in a more compact molecular packing with a smaller tilting angle. Chemistry Stack Exchange is a question and answer site for scientists, academics, teachers, and students in the field of chemistry. Most other phosphates are only slightly soluble or are insoluble in water. This molecule is made up of three phosphate groups and adenosine. In addition, the range 14301820cm1 shows characteristic features. This substitution pattern is symmetric, and careful chemical and 31P-n.m.r. The phosphate groups of nucleotides may be replaced by isosteres, the replacement of the base portion is often exploited in the development of structureactivity relationship (SAR) [170]. M.H. Thanks for contributing an answer to Chemistry Stack Exchange! The energy possessed by the ATP molecule resides in the chemical bonds of the phosphate group. While the bilayer is most practical as a two dimensional planar structure, it can fold in on itself to form a closed, vesicle called a liposome. DNA is basically a polymer of nucleotides. [97], the iridoids are found into Lamiids, which contain iridoids of Gentianales, Lamiales Gallyales order, and into Campanulids, which contain secoiridoids of Asterales and Dipsacales order. Recently, the intercalation procedure has been employed in food science to increase the stability and applicability of additives. This makes a sugar-phosphate backbone with those important bases (like adenine, thymine, and so on) hanging off. An MS-based phosphatase or kinase assay using MALDI-MS or ESI-MS analysis of intact phosphoproteins is a simple and straightforward method for monitoring the state of PTM, particularly for abundant (recombinant) proteins [32,33]. When an electrically charged molecule is combined with mineral phosphorus, it is considered part of the phosphate group. Phone: (480) 413-1499 Text: To study molecular association processes and large-scale conformational changes are being accomplished through the use of course-grained (CG) model and several CG models have been implemented in current MD or Brownian dynamics (BD) software (3841). Working your way through this lesson should help you complete the following: To unlock this lesson you must be a Study.com Member. The carbon atom chain to the right of the carbonyl group is part of the acid. At physiological pH, the protons in the OH groups of these esters are ionized. Many diseases are triggered by some defects present in the enzymes that transfer the phosphate. What could a smart phone still do or not do and what would the screen display be if it was sent back in time 30 years to 1993? Darder et al.54 prepared composites of LDHs with natural biopolymers such as alginic acids, pectin, carrageenan, and others by both the coprecipitation and the coorganized assembly routes. The structural complexity of the membrane bilayer goes beyond a single type of phospholipid molecule. 215 lessons. 6). This addition changes the nucleoside from a base to an acid. When the third hydroxyl group of the glycerol is bound to a charged molecule such as phosphate instead of a hydrocarbon chain, the diacylglycerol is known as a phospholipid. Accessibility StatementFor more information contact us [email protected] check out our status page at https://status.libretexts.org. Noniridoids arise from the oxidative decarboxylation on C-10 or C-11 of the iridoid glycoside skeleton [99103]. When two phosphate groups are bonded to one another, the bond is called phosphate anhydride and the compound formed is inorganic pyrophosphate. Phosphate groups are available in energy molecules other than ATP, but these are not very common. When you contract your muscles, for example, your muscle proteins use ATP to do it. Phosphoserine and phosphothreonine residues undergo partial gas phase -elimination of phosphoric acid (H3PO4, 98Da), in MALDI-TOF-MS and ESI-MS resulting in conversion into dehydroalanine residue (69Da) and dehydroaminobutyric acid residue (83Da), respectively. Carbocyclic nucleosides represent an interesting group of nucleoside analogues; from a chemical and biological point of view, the substitution of the oxygen atom with a methylene group in the furanose moiety improves the chemical and metabolic stability, while the biological activity could be maintained in some carbocyclic compounds. Ethanolamine is both a primary amine and alcohol, and attaches to the PA head group via the hydroxyl. Why does phosphate have a charge of 3? This PTM has the potential to alter the stability, subcellular location, and enzymatic activity of proteins with diverse roles in cells. (7), Phosphatidylinositol (PI) is a unique phospholipid in that the head group is a cyclohexane carbohydrate called inositol, which is attached to the phosphate moiety at the 1 carbon. Together, these chemical groups constitute an energy powerhouse. in Plant Sciences from University of Hyderabad, India and a Master of Philosophy degree from Annamalai University. The extent of phosphate substitution is influenced by, for instance, the growth conditions(122124). These are held together by covalent bonds formed between the phosphate groups, each of which forms and ester with a hydroxyl group of the pentose of the NEXT nucleotide. The X-ray diffraction pattern of these LDHs suggests that the interlayer orientation of fatty acids forms a close zig-zag packing of linear molecules.
