A phosphoglycerate is always made up of:

Options

(a) only an unsaturated fatty acid esterified to a glycerol molecule to which a phosphate group is also attached
(b) a saturated or unsaturated fatty acid esterified to a glycerol molecule to which a phosphate group is also attached
(c) a saturated or unsaturated fatty acid esterified to a phosphate group which is also attached to a glycerol molecule
(d) only a saturated fatty acid esterified to a glycerol molecule to which a phosphate group is also attached

Correct Answer:

a saturated or unsaturated fatty acid esterified to a glycerol molecule to which a phosphate group is also attached

Explanation:

A saturated or unsaturated fatty acid esterified to a glycerol molecule to which a phosphate group is also attached forms phosphoglycerides. Phosphoglycerides are major structural components of cell membranes. They are, therefore, also called membrane lipids. Lecithin is one example.
