Description

Gamma-Hydroxybutyric acid (GHB) is a naturally occurring neurotransmitter and a psychoactive drug. This compound is a precursor to GABA, glutamate, and glycine in certain brain areas, acts on the GHB receptor and is a weak agonist at the GABAB receptor.

GHB has been used in a medical setting as a general anesthetic and as a treatment for cataplexy, narcolepsy, and alcoholism. It is also used illegally as an intoxicant, to try to increase athletic performance, and as a date rape drug. GHB is also produced as a result of fermentation, and is found in small quantities in some beers and wines, beef and small citrus fruits. Succinic semialdehyde dehydrogenase deficiency is a disease that causes GHB to accumulate in the blood.

Part of this pathway was inspired by Chapter 5 of the book of Blau (ISBN 3642403360 (978-3642403361)), Fig. 5.3.
