Vedclass · Answer

(A) An amino acid contains both an amino group $(-NH_2)$ which is basic and a carboxyl group $(-COOH)$ which is acidic. Due to the presence of both acidic and basic groups,amino acids can act as both acids and bases depending on the $pH$ of the solution. This dual nature is known as amphoteric nature. Therefore,amino acids are considered amphoteric substances.
