Q. A phosphoglyceride is always made up of
A) Only a saturated fatty acid esterified to a glycerol molecule to which a phosphate group is also attached
B) Only an 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 glycerol molecule to which a phosphate group is also attached
D) A saturated or unsaturated fatty acid esterified to a phosphate group which is also attached to a glycerol molecule
Explanation
[Solution from source] In a phosphoglyceride (e.g. lecithin), fatty acids, which may be saturated or unsaturated, are esterified to glycerol, and the glycerol also carries a phosphate group. The fatty acid is not esterified to the phosphate, and it need not be only saturated or only unsaturated. Answer (3).
