Descriptions:
pubchem: Alpha-aminobutyric acid is an alpha-amino acid that is butyric acid bearing a single amino substituent located at position 2. It has a role as a human metabolite. It is a monocarboxylic acid and a non-proteinogenic alpha-amino acid. It is functionally related to a butyric acid. It is a conjugate acid of an alpha-aminobutyrate.
chebi: An α-amino acid that is butyric acid bearing a single amino substituent located at position 2.
chembl: Unnamed Compound is a small molecule listed in the ChEMBL database but has not progressed to an approved clinical phase.
wikipedia: α-Aminobutyric acid (AABA), also known as homoalanine in biochemistry, is a non-proteinogenic alpha amino acid with chemical formula C4H9NO2. The straight two carbon side chain is one carbon longer than alanine, hence the prefix homo-.  The conjugate base of α-aminobutyric acid is the carboxylate α-aminobutyrate.
Homoalanine is biosynthesized by transaminating oxobutyrate, a metabolite in isoleucine biosynthesis. It is used by nonribosomal peptide synthases. One example of a nonribosomal peptide containing homoalanine is ophthalmic acid, which was first isolated from calf lens.
α-Aminobutyric acid is one of the three isomers of aminobutyric acid. The two other are the neurotransmitter γ-aminobutyric acid (GABA) and β-aminobutyric acid (BABA) which is known for inducing plant disease resistance.
This amino acid has been detected in meteorites.
