Vedclass · Answer

(A) Amino acids consist of an amine group $(-NH_2)$ and a carboxyl group $(-COOH)$ attached to the same alpha-carbon atom.An amino acid is optically active if the alpha-carbon is chiral,meaning it is bonded to four different groups.Glycine,with the structure $H_2N-CH_2-COOH$,has two hydrogen atoms attached to the alpha-carbon.Since the alpha-carbon is not bonded to four different groups,it is achiral.Therefore,$Glycine$ is the only optically inactive amino acid among the $20$ common amino acids.

Which of the following amino acids is optically inactive?
