Metabolite Identification
Common NameD-Alpha-aminobutyric acid
DescriptionD-alpha-Aminobutyric acid, also known as a-aminobutyrate or (R)-2-aminobutanoic acid, belongs to the class of organic compounds known as d-alpha-amino acids. These are alpha amino acids which have the D-configuration of the alpha-carbon atom. D-alpha-Aminobutyric acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
