HUMAN NUTRITION

Detailed explanation-1: -Phospholipids (PL) are a group of polar lipids that consist of two fatty acids, a glycerol unit and a phosphate group which is esterified to an organic molecule (X) such as choline, ethanolamine, inositol, etc.

Detailed explanation-2: -Like triglycerides, phospholipids have a glycerol backbone. But unlike triglycerides, phospholipids only have two fatty acid molecules attached to the glycerol backbone, while the third carbon of the glycerol backbone is bonded to a phosphate group-a chemical group that contains the mineral phosphorus.

Detailed explanation-3: -Triglycerides and phospholipids are two groups of lipid. Triglycerides are formed by the condensation of one molecule of glycerol and three molecules of fatty acid. A condensation reaction between glycerol and a fatty acid (RCOOH) forms an ester bond. The R-group of a fatty acid may be saturated or unsaturated.
