Detailed explanation-1: -Amino acids differ from each other with respect to their side chains, which are referred to as R groups. The R group for each of the amino acids will differ in structure, electrical charge, and polarity.
Detailed explanation-2: -R group: The R group is a side chain specific to each amino acid that confers particular chemical properties to that amino acid. polypeptide: Any polymer of (same or different) amino acids joined via peptide bonds.
Detailed explanation-3: -Amino acids are made up of a central carbon bonded to an amino group (–NH2), a carboxyl group (–COOH), and a hydrogen atom. The central carbon’s fourth bond varies among the different amino acids, as seen in these examples of alanine, valine, lysine, and aspartic acid.
