Proteins are a macromolecule that consists of monomers called amino acids, and polymers that are a called polypeptides. These proteins are made up of carbons, hydrogens, oxygens, nitrogen's, and sulphur's. Proteins functions can be divided in to two areas, regulatory proteins and structural proteins. Regulatory proteins are enzymes, messenger hormones, and defence antibodies that help regulate cells. Structural proteins help with movement and build structure, as hair, cell membranes, and muscle fibers all consists of these structural proteins.
