Photograph of gamma-Aminobutyric Acid under the microscope.

gamma-Aminobutyric acid (GABA) is the product of a biochemical decarboxylation reaction of glutamic acid by the vitamin pyridoxal. GABA serves as a inhibitory neurotransmitter to block the transmission of an impulse from one cell to another in the central nervous system. Medically, GABA has been used to treat both epilepsy and hypertension where it is thought to induce tranquility in individuals who have a high activity of manic behavior and acute agitation.
