$(-NH_2)$

Vedclass · Answer

(A) An amino acid is an organic compound that contains both an amino group $(-NH_2)$ and a carboxyl group $(-COOH)$ attached to the same carbon atom,known as the $\alpha$-carbon.In this structure,the amino group $(-NH_2)$ acts as a base because the nitrogen atom has a lone pair of electrons that can accept a proton $(H^+)$.Conversely,the carboxyl group $(-COOH)$ acts as an acid because it can donate a proton $(H^+)$.Therefore,the basic group in an amino acid is the amino group $(-NH_2)$.
