Phospholipids are esters of glycerol with
A
one carboxylic acid residue and two phosphate groups
B
three phoshate groups
C
three carboxylic acid residues
D
two carboxylic acid residues and one phosphate groups
Answer
two carboxylic acid residues and one phosphate groups
Explanation
Solution
Phospholipids are esters of glycerol with two carboxylic acid residue and one phosphate group. Hence, phospholipids may be regarded as derivative
of glycerol in which two hydroxyl groups are esterified with fatty acid, while third is esterified with phosphoric acid.
