DL-3-Aminoisobutyric acid Chemical Properties, Uses, Production

Uses

DL-3-Aminoisobutyric Acid Hydrate is a beta-amino acid used for proteomics research.

Definition

ChEBI: 3-aminoisobutyric acid is a beta-amino-acid that is isobutyric acid in which one of the methyl hydrogens is substituted by an amino group. It has a role as a metabolite. It is functionally related to an isobutyric acid. It is a conjugate acid of a 3-aminoisobutyrate. It is a tautomer of a 3-aminoisobutanoic acid zwitterion.

General Description

DL-3-Aminoisobutyric acid (for short, 3AIBA), synonymous with α-Methyl-β-alanine, is a β-amino acid occurring naturally in all living organisms. 3AIBA can be formed in humans and animals from the nucleotide thymine and amino acid valine. Since 3AIBA is structurally similar to β-alanine; it can also be called α-methyl-β-alanine having one additional methyl group on α-carbon atom. In their free form, β-alanine and 3AIBA are metabolites in mammals and moieties in several pharmacologically active compounds such as antibiotics, antitumor, and antifungal agents[1].
