There are actually 20 different amino acids, each one distinct in an R-group side chain. Did you mean what are the four parts of amino acids called? Because if so, they would be an amine (N) terminus (The NH2), carboxyl (C) terminus (The COOH), an H group of just a hydrogen atom, and an R group which is unique for each amino acid and identifies it from other amino acids. These four groups are bound to a central carbon atom.
