Interpretation:
The organic compounds produced by the complete hydrolysis of the given compounds need to be identified.
Concept Introduction:
>Phospholipids are derived from phosphatidic acid. The phosphatidic acid has two hydroxyl groups of a glycerol unit, joined to fatty acids through ester linkages. The other terminal hydroxyl group is joined to the phosphoric acid through an ester linkage.
>When the phosphate group of the phosphatidic acid is connected to a nitrogen containing compound such as choline, 2-aminiethanol and L-serine through another phosphate ester linkage, a phosphatide is formed. Lecithin, cephalin, phosphatidylserines and plasmalogens are important groups of phosphatides.
>Lecithin finds wide application in food industry. To enhance their compatibility and performance with the product they are used with, lecithin molecules are hydrolyzed enzymatically.
>The hydrolysis of lecithin results in the production of glycerol, fatty acids, phosphoric acid, and choline molecules
>The hydrolysis of cephalin results in the breakdown of carboxy ester and phosphoester bonds to produce glycerol, fatty acids, phosphoric acid, and ethanolamine molecules.
>The hydrolysis of choline-based plasmalogen gives glycerol, fatty acid, phosphoric acid, and an unsaturated
