Vedclass · Answer

(B) An amino acid is optically active if it contains at least one chiral carbon atom (an asymmetric carbon atom bonded to four different groups).Glycine has the structure $NH_2-CH_2-COOH$. Since the central carbon atom is bonded to two identical hydrogen atoms,it is achiral and therefore optically inactive.All other naturally occurring amino acids have at least one chiral carbon atom (the $\alpha$-carbon) and are thus optically active.Therefore,the statement 'All amino acids except glycine are optically active' is correct.
