Vedclass · Answer

(D) The isoelectric point $(pI)$ is the $pH$ at which an amino acid carries no net electrical charge.At this $pH$,the amino acid exists as a dipolar ion,commonly known as a zwitterion.In a zwitterion,the carboxyl group loses a proton to become a carboxylate ion $(COO^{-})$ and the amino group gains a proton to become an ammonium ion $(NH_3^{+})$.Therefore,the structure is $H_3N^{+} - CHR - COO^{-}$.
