Phosphorus is not a component of each monomer used to make proteins. While some amino acids may contain an additional phosphate group, it is not a universal component and not present in every amino acid. The essential components of amino acids that make up proteins are the amino functional group (NH₂), the carboxyl group (COOH), and the side chain (R).
