Metabolite Identification
Common NameD-alpha-Aminobutyric acid
DescriptionD-alpha-Aminobutyric acid is the D-isomer of alpha-aminobutyric acid. The L-form of this amino acid is used in the biosynthesis of ophthalmic acid (a tripeptide analogue of glutathione in which the cysteine group is replaced by L-2-aminobutyrate, which was first discovered and isolated from calf lens). The D-form of this amino acid is a substrate for D-amino acid oxidase. There is little evidence that the D-form of this amino acid is found in human biofluids or tissues. What little does exist is likely of bacterial origin.
