Metabolite Identification
Common Name3-Aminobutanoic acid
Description3-Aminobutanoic acid, also known as 3-methyl-beta-alanine or beta-aminobutyric acid, belongs to the class of organic compounds known as beta amino acids and derivatives. These are amino acids having a (-NH2) group attached to the beta carbon atom. 3-Aminobutanoic acid has been detected, but not quantified in, a few different foods, such as breakfast cereal, cereals and cereal products, and milk (cow). This could make 3-aminobutanoic acid a potential biomarker for the consumption of these foods. 3-Aminobutanoic acid is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review a significant number of articles have been published on 3-Aminobutanoic acid.
