Vedclass · Answer

(D) Amino acids are organic compounds containing an amino group $(-NH_2)$ and a carboxyl group $(-COOH)$.$1$. They are amphoteric in nature because they possess both acidic $(-COOH)$ and basic $(-NH_2)$ groups,allowing them to react with both acids and bases.$2$. At the isoelectric point $(pI)$,the amino acid exists as a zwitterion,where the molecule has a net charge of zero (the $-NH_2$ group is protonated to $-NH_3^+$ and the $-COOH$ group is deprotonated to $-COO^-$).$3$. Amino acids are the fundamental building blocks (monomeric units) of proteins,linked together by peptide bonds.Since all the given statements are correct,the correct option is $D$.
