Using recombinant DNA technology, the present study provides the first strong and direct evidence indicating that β-alanine is an efficient substrate for the mammalian transaminating enzymes 4-aminobutyrate-2-oxoglutarate transaminase and alanine-glyoxylate transaminase. The concentration of carnosine and anserine in murine skeletal and heart muscle depends on circulating availability of β-alanine, which is in turn controlled by degradation of β-alanine in liver and kidney. Chronic oral β-alanine supplementation is a popular ergogenic strategy in sports because it can increase the intracellular carnosine concentration and subsequently improve the performance of high-intensity exercises. The present study can partly explain why the β-alanine supplementation protocol is so inefficient, by demonstrating that exogenous β-alanine can be effectively routed toward oxidation.
