Vedclass · Answer

(B) Amino acids are classified based on the nature of their '$R$' group. Acidic amino acids (e.g.,Aspartic acid,Glutamic acid) contain an extra carboxyl group $(-COOH)$ in their side chain. At physiological $pH$,this carboxyl group dissociates to form a carboxylate ion $(-COO^-)$,which imparts a negative charge to the '$R$' group. Therefore,acidic amino acids are characterized by having a polar,negatively charged '$R$' group.
