  1. A phosphoglycerate is always made up of :
    1. only an unsaturated fatty acid esterified to a glycerol molecule to which a phosphate group is also attached
    2. a saturated or unsaturated fatty acid esterified to a glycerol molecule to which a phosphate group is also attached
    3. a saturated or unsaturated fatty acid esterified to a phosphate group which is also attached to a glycerol molecule.
    4. only a saturated fatty acid esterified to a glycerol molecule to which a phosphate group is also attached
Correct Option: B

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, called membrane lipids. Lecithin is one such example.
