The amino acids that go into making proteins are so-called alpha-amino acids. This is because they have an amino group (-NH2) on the carbon atom just next to the carboxyl group (-COOH). The simplest such amino acid is glycine, H2N-CH2-COOH. Another simple one is alanine, CH3-CH(-NH2)-COOH (three carbons, the NH2 group on the second one). There are about 22 amino acids that go into the making of proteins. Some are essential: This means that the body cannot make them, and they are needed in the diet. Others are nonessential: The body can make glycine and alanine from other raw materials.
