HUMAN NUTRITION

Detailed explanation-1: -Saponifiable lipids can also be divided into groups: Simple lipids (fatty acid+ alcohol) and includes waxes and triglyceride. Complex lipids (fatty acid + alcohol + other compounds) and includes phosphoglycerides and sphingolipids.

Detailed explanation-2: -Phospholipids. Phospholipids consist of four components: fatty acids, glycerol or sphingosine, phosphate, and alcohol attached to phosphate. It includes phosphoglycerides, ether glycerophospholipids, and sphingophospholipids.

Detailed explanation-3: -Saponifiable lipids contain at least one ester group, which undergoes hydrolysis in the presence of an acid, a base, or an enzyme. Hydrolysis cleaves a saponifiable lipid into two or more smaller molecules. Nonsaponifiable lipids do not undergo hydrolytic cleavage into smaller molecules.
