Beta alanine is a naturally occurring beta amino acid, which are amino acids in which the amino group is at the β-position from the carboxylate group. 
β-Alanine is not used in the biosynthesis of any major proteins or enzymes. It is formed in vivo by the degradation of dihydrouracil and carnosine. It is a component of the naturally occurring peptides carnosine and anserine and also of pantothenic acid (vitamin B5) which itself is a component of coenzyme A. Under normal conditions, β-alanine is metabolized into acetic acid.
