Alanine (L-Alanine) is an α-amino acid that is used for protein biosynthesis. Approximately 8% of human proteins have alanine in their structures. The reductive lamination of pyruvate is effected by alanine transaminase. L-Alanine can be converted to pyruvic acid by alanine aminotransferase 1 reversibly coupled with interconversion of oxoglutaric acid and L-glutamic acid. L-Alanine can also be produced by alanine-glyoxylate transaminase with coupled interconversion of glyoxylate and glycine. L-Alanine will be coupled with alanyl tRNA by alanyl-tRNA synthetase to perform protein biosynthesis. Alanine can also be used to provide energy under fasting conditions. There are two pathways that can facilitate this: (1) alanine is converted to pyruvate to synthesize glucose via the gluconeogenesis pathway in liver tissue or (2) alanine converted into pyruvate moves into the TCA cycle to be oxidized in other tissues.
