Description and Uses

L-Alanine is a non-essential amino acid. It is produced by direct β-decarboxylation of L-aspartate by L-aspartate β-decarboxylase or transamination of pyruvate in the glucose-alanine cycle and is a precursor for gluconeogenesis. Dysregulation of L-alanine metabolism is associated with various disease states, including diabetes, metabolic syndrome, ketotic hypoglycemia, and acquired acute lactic acidosis.

L-Alanine plays a vital role in glucose-alanine cycle between tissue and liver. It is used for protein construction as well as involved in the metabolism of tryptophan and vitamin pyridoxine. It provides energy for muscles and central nervous system in order to strengthen the immune system. It helps in the metabolism of sugars and organic acids, and enhances the germination rates of Bacillus subtilis spores. It also displays a cholesterol-reducing effect in animals.
