Glycerol structural formula

Write the structural formula for the product of (a) the reaction of glycerol (1,2,3-trihydroxypropane) with stearic acid, CH5(CH2)16COOH, to produce a saturated fat (b) the oxidation of 4-hydroxybenzyl alcohol by sodium dichromate in an acidic organic solvent. 

Sulfonic acids and sulfonate salts contain the -S03H and -SO) groups, respectively, attached to a hydrocarbon moiety. The structural formulas of benzene sulfonic acids and of sodium 1 -(p-sulfophenyl)decane, a biodegradable detergent surfactant, are shown in Figure 1.19. The common sulfonic acids are water-soluble strong acids that lose virtually all ionizable H+ in aqueous solution. They are used commercially to hydrolyze fat and oil esters to produce fatty acids and glycerol used in chemical synthesis. 

It it appropriate at this point to provide a general description of the types of phospholipids one encounters in mammalian cells and those which we will be considering in this book. Essentially there are two major classes of phospholipids, one of which contains a glycerol backbone and the other of which contains a sphingosine backbone. Their general structural formulae are presented in Figure 1-5. 

Structural formula A is typical of a group of compounds commonly called phosphoglycerides. In this particular depiction the symbols R1 and R2 are long-chain carboxylic acids linked in an ester linkage to the primary and secondary alcohol residues of glycerol. The symbol X is a mixed venue with a wide variety of bases—for example, choline (HOCH2CH2 N (CH3)3) or... 

Glycerin, also spelled glycerine, which is also called glycerol, has the empirical formula C3Hg03 or C3H3(OH)3 and the following structural formula ... 

The structural formulas of phosphatidyl choline and the other principal phosphoglycerides—namely, phosphatidyl ethanolamine, phosphatidyl serine, phosphatidyl inositol, and diphosphatidyl glycerol—are given in Figure 12.5. 

PROBLEM 15.10 Alfred Nobel s fortune was based on his 1866 discovery that nitroglycerin, which is far too shock-sensitive to be transported or used safely, can be stabilized by adsorption onto a substance called kieselguhr to give what is familiar to us as dynamite. Nitroglycerin is the trinitrate of glycerol (1,2,3-propanetriol). Write a structural formula or construct a molecular model of nitroglycerin. 

Molecules with complex structures, which do not "slide" smoothly past each other, and polar molecules, tend to have higher viscosity than less structurally complex, less polar liquids. Glycerol, which is used in a variety of skin treatments, has the structural formula ... 

II) Glycerol, or propane-1,2,3-triol, is used in many cosmetic preparations to make them feel soft. Write its structural formula. 

Write the structural formula of a fat derived from the esterification reaction of one molecule of glycerol and three molecules of octadecanoic acid ( octadec = 18). 

The osmotic pressure of an aqueous glycerol solution is FI = 12 bar. Estimate the glycerol concentration of the solution. The structural formula of glycerol is CH2OH-CHOH-CH2OH. 

Write structural formulas for glycerol, stearic acid, palmitic acid, oleic acid, and linoleic acid. 

Draw the condensed structural formula for a wax or triacylglycerol produced by the reaction of a fatty acid and an alcohol or glycerol. 

Draw the condensed structural formula for a mixed triacylglycerol that contains two palmitic acid molecules and one oleic acid molecule on the second carbon (center carbon) of glycerol. 

Tnmynstm is obtained from coconut oil and has the molecular formula C45H86O6 On being heated with aqueous sodium hydroxide followed by acidification trimyristin was converted to glycerol and tetradecanoic acid as the only products What is the structure of trimyristin ... 

On the basis of trimyristin s molecular formula C45H8606 and of the fact that its hydrolysis gives only glycerol and tetradecanoic acid CH3(CH2)12C02H, it must have the structure shown. 

The stereodescriptor sn indicates that the name results from the convention of stereospecific numbering of the atoms of glycerol. The structure must therefore be drawn as a Fischer projection formula with the l configuration. 

Glycerine (sometimes called glycerin ) is the name of the commercial product consisting of glycerol and a small amount of water. Glycerol is actually trihydric alcohol C2H5(0H)3, which is more accurately named 1,2,3-propanetriol. Its chemical structure is shown in the formulas given below.
