Vedclass · Answer

(B) Glycine is the simplest amino acid with the formula $NH_2-CH_2-COOH$. In an aqueous solution,the acidic carboxyl group $(-COOH)$ loses a proton to the basic amino group $(-NH_2)$. This internal proton transfer results in the formation of a dipolar ion known as a zwitter ion. The structure of the glycine zwitter ion is $H_3N^{+}-CH_2-COO^{-}$.
