Metabolite Identification
Common NameN-Acetyl-beta-alanine
DescriptionN-Acetyl-beta-alanine, also known as 3-(acetylamino)propanoate, belongs to the class of organic compounds known as carboxylic acids. Carboxylic acids are compounds containing a carboxylic acid group with the formula -C(=O)OH. N-Acetyl-beta-alanine is the N-acetyl derivative of beta-alanine. It is therefore also classified as an N-acetyl-amino acid and a beta-alanine derivative. It is a substrate for the enzyme called N-acetyl-beta-alanine deacetylase, which converts N-acetyl-beta-alanine into acetate and beta alanine (https://doi.org/10.1016/0005-2744(68)90220-9). N-Acetyl-beta-alanine has also been found in coffee (PMID: 31582163 ). It appears that N-Acetyl-beta-alanine exists in all living organisms, ranging from bacteria to plants to humans.
