Metabolite Identification
Common Name3-Aminoisobutanoic acid
Description3-Aminoisobutanoic acid, also known as b-aminoisobutyrate or 2-methyl-beta-alanine, 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-Aminoisobutanoic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. 3-Aminoisobutanoic acid exists in all eukaryotes, ranging from yeast to humans. 3-aminoisobutanoic acid can be biosynthesized from ureidoisobutyric acid; which is mediated by the enzyme Beta-ureidopropionase. In humans, 3-aminoisobutanoic acid is involved in the metabolic disorder called the beta-ureidopropionase deficiency pathway. Outside of the human body, 3-Aminoisobutanoic acid has been detected, but not quantified in, milk (cow). This could make 3-aminoisobutanoic acid a potential biomarker for the consumption of these foods. 3-Aminoisobutanoic acid is a potentially toxic compound. A beta-amino-acid that is isobutyric acid in which one of the methyl hydrogens is substituted by an amino group.
