Which of the following acids is a vitamin ?

(A)Adipic acid
(B)Aspartic acid
(C)Ascorbic acid✓ Correct
(D)Saccharic acid

Answer: (C)

Solution

Adipic acid is a dicarboxylic acid used in nylon-66 synthesis, aspartic acid is a proteinogenic amino acid, and saccharic acid is an oxidised sugar derivative — none of these is a vitamin. Ascorbic acid is vitamin C, essential for collagen synthesis and acting as a biological antioxidant.
