Metabolite Identification
Common NameGamma-Aminobutyric acid
DescriptionGamma-Aminobutyric acid, also known as gaba or g-amino-butanoate, belongs to the class of organic compounds known as gamma amino acids and derivatives. These are amino acids having a (-NH2) group attached to the gamma carbon atom. Gamma-Aminobutyric acid exists as a solid, very hydrophobic, practically insoluble (in water), and relatively neutral molecule. Gamma-Aminobutyric acid exists in all living species, ranging from bacteria to humans. Gamma-Aminobutyric acid is a potentially toxic compound.
