Amino acids are organic compounds that contain amine (-NH2) and carboxyl (-COOH).

Elements of an amino acid are carbon (C), hydrogen (H), oxygen(O), and nitrogen.

Proteins are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues.

Metalloprotein is a generic term for a protein that contains a metal ion cofactor.
