Vedclass · Answer

(B) An amino acid is achiral if it does not possess a chiral carbon atom (a carbon atom bonded to four different groups). Glycine $(NH_2-CH_2-COOH)$ is the only naturally occurring achiral amino acid because its $\alpha-$carbon is bonded to two hydrogen atoms. $2-$Methylglycine,also known as $\alpha-$aminoisobutyric acid $(NH_2-C(CH_3)_2-COOH)$,is also achiral because the $\alpha-$carbon is bonded to two identical methyl groups. Therefore,$2-$Methylglycine is an achiral amino acid.
