As shown, its alpha carbon atom is bonded to a carboxyl group (COO-), an amino group (NH3+), a methyl group (CH3), and a hydrogen atom. It exists as two distinct enantiomers, L-alanine and D-alanine, the former of which is used in protein synthesis. It is derived, for example, from silk. Alanine aminopeptidase (AAP) is an enzyme used as a biomarker to detect damage to the kidneys, and that may be used to help diagnose certain kidney disorders. It is found at high levels in the urine when there are kidney problems. Alanine transferase (also called serum glutamate pyruvate transaminase or SGPT) is an enzyme found in the liver and other tissues. A high level of alanine transferase released into the blood may be a sign of liver damage, cancer, or other diseases.
