How do you explain the amphoteric behaviour of amino acids ?

Text Solution

Verified by Experts

Amino acids contain an acidic (carboxyl group) and basic (amino group) group in the same molecule. In aqueous solution, they neutralize each other. The carboxyl group loses a proton while the amino group accepts it . As a result, a dipolar or zwitter ion is formed. In zwitter ionic form, a-amino acid show amphoteric behaviour as they react with both acids and bases.
