| Amino acids (n=20) are abbreviated either by a three or one letter format that is used when referring to long protein chains. Each amino acid has at least one amine and one acid functional group. Amino acids based on the structures of different amino acid side chain (R groups) exhibit different properties which are basic, acidic, or neutral and based on the net electric charge are either polar or non-polar. | |||
