None
Ans. is 'a' i.e., Carboxyl groupThe acid base propeies of amino acids depend on the amino and carboxyl groups attached to the a-carbon.The carboxyl (-COOH) group of an amino acid can donate protein (H') and behave as an acid forming a negatively charged anion (C00-).Amino group (-NH) can accept proton (H') and behave as a base, forming positively charged cation (NH3').
