The basic building block of a protein is called an amino acid. There are 20 amino acids in the proteins you eat and in the proteins within your body, and they link together to form large protein molecules. The variety of ways they mix and match allows for the great diversity of proteins in nature. Understanding the structure of amino acids and how they relate to the proteins they create can help you appreciate how critical these nutrients are in your diet.
The Building Blocks: Amino Acids
Although each of the 20 amino acids is different, the basic structure follows a similar pattern. Amino acids all contain a carbon atom in the middle of the molecule, which is surrounded by three chemical groups. Two of these chemical groups, a carboxyl group and an amino group, are also the same in all amino acids. The third group, however, differentiates each amino acid from the others. These R-groups can be as simple as a single hydrogen atom, as in the amino acid glycine, or as complex as the double-ring structure found in tryptophan. The chemical differences in the R-groups affect the interplay of amino acids within a protein.
