Vedclass · Answer

(C) In an aqueous solution,the carboxyl group $(-COOH)$ of an amino acid can lose a proton to form a carboxylate ion $(-COO^-)$,and the amino group $(-NH_2)$ can accept a proton to form an ammonium ion $(-NH_3^+)$. This internal proton transfer results in the formation of a dipolar ion known as a zwitterion,represented as $H_3N^+-CHR-COO^-$. Therefore,amino acids exist as zwitterions in aqueous solutions.
