WebA protein’s structure is primarily made up of long chains of amino acids. The arrangement and placement of amino acids give proteins certain characteristics. All amino acid molecules contain an amino (-NH2) and a carboxyl (-COOH) functional group. Hence, the name “Amino-Acid”. Polypeptide chains are synthesized by linking together amino acids.
