. How do you explain the amphoteric behavior of amino acids
Best Answer
Amino acids have amino (—NH2) group, basic in nature and carboxyl (—COOH) group which is acidic in nature. In queous medium, NH2 group accepts a proton and COOH group loses a proton forming a dipolar ion, called the Zwitter ion. In this form, amino acids behave both as acids and bases so they are amphoteric in nature.
