The amino acid which is not optically active is

A

lactic acid

B

serine

C

alanine

D

glycine

Text Solution

Verified by Experts

The correct Answer is:
D
Glycine
Except glycine, all `alpha`-amino acids are optically active and have an asymmetric carbon atom. Hence each of these amino acids can exist in two optical isomeric forms.

It also possesses an asymmetric carbon atom.Therefore it is also optically active.
