L-2-Aminobutyric acid, CAS 1492-24-6, Homoalaine

What is L-2-Aminobutyric acid? In biochemistry, L-2-Aminobutyric acid is also known as homoalanine. It is a non-proteinogenic alpha amino acid. The straight two carbon side chain is one carbon longer than alanine, hence the prefix homo-. L-2-Aminobutyric acid is an isomer of the amino acid aminobutyric acid. It has two other isomers, gamma-aminobutyric acid (GABA) and beta-aminobutyric acid. In contrast, GABA is a neurotransmitter and not used in protein synthesis, and it is almost always referred to as GABA. Application of L-2-Aminobutyric acid L-2-Aminobutyric acid is an intermediate for medicine. Synthesis of L-2-Aminobutyric acid Homoalaine is biosynthesised 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.
