Beta Alanine and Carnosine
Beta Alanine in sports is used for its peculiarity as an anti-fatigue and ergogenic, a characteristic attributable partly to its antioxidant activity and partly to its ability to regenerate muscle Carnosine.
Beta-Alanine is a nonessential amino acid, that is, it cannot be synthesized from Alanine through specific enzymatic pathways.
In contrast to the vast majority of other amino acids, however, the amino group is in the Beta position with respect to the acidic carbon (the one bound to the carboxyl group) instead of in the alpha position: hence the name Beta Alanine
Unlike its alpha counterpart (α-alanine), B-alanine lacks a chiral center (meaning that the L and R forms typical of ordinary amino acids do not exist). It also does not participate to any appreciable extent in protein synthesis.
