Vedclass · Answer

(A) An amino acid is chiral if it has a chiral carbon atom (an $\alpha$-carbon bonded to four different groups). All naturally occurring $\alpha$-amino acids are chiral except for Glycine. Glycine has the structure $NH_2-CH_2-COOH$,where the $\alpha$-carbon is bonded to two hydrogen atoms,making it achiral. Valine,Alanine,and Proline all possess a chiral center at the $\alpha$-carbon.
