D Devendra Khairwa

Amino acid has both acidic group  (C=O)\left  and basic group (N-H). Thus in aqueous solution, the carboxyl group can lose a proton and the basic group (amine group) can accept a proton. In this way, it forms zwitter ion which can act in both ways i.e., acidic as well as basic. Hence amino acids are amphoteric in nature.
