ChEBI: An optically active form of alpha-aminobutyric acid having L-configuration. | [Synthesis Reference(s)]
Journal of the American Chemical Society, 68, p. 450, 1946 DOI: 10.1021/ja01207a032 | [General Description]
L-2-Aminobutyric acid is synthesized from L-threonine and L-aspartic acid through a ?-transamination reaction. It is an L-alanine analogue with an ethyl side chain. | [Biochem/physiol Actions]
L-α-Aminobutyric acid (AABA) is an isomer of the non-natural amino acid aminobutyric acid with activity in the γ-glutamyl cycle that regulates glutathione biosynthesis. Recently AABA has been studied as a supplement to in vitro maturation medium (NCSU 23 medium) for culture of oozytes and embryos. This product has been qualified for use in cell culture. AABA is also used as a substitute amino acid for alanine in studies on peptide function. | [storage]
