Proteins are macromolecules that are composed of amino acids, and a single protein molecule may contain as many as 5,000 amino acid molecules. The amino acids that make up the protein molecule constitute its primary structure. The interactions between these amino acids form the protein's secondary structure. Both of these structures are important in proteins as the function of proteins is highly dependent on their shape.
