Γ-Hydroxyvaleric acid

Γ-Hydroxyvaleric acid (also known as GHB or gamma-hydroxybutyrate) is a naturally occurring neurotransmitter and a psychoactive drug. It is found in the human body and in many other animals. The substance can be used as a recreational drug, as a treatment for narcolepsy, and as a supplement for bodybuilding.

Chemistry

Γ-Hydroxyvaleric acid is a carboxylic acid with a four-carbon chain. The third carbon in the chain has a hydroxyl group attached, hence the name "gamma-hydroxy". The substance is a weak acid, with a pKa of 4.72. It is soluble in water and has a slightly sweet taste.

Pharmacology

In the human body, Γ-Hydroxyvaleric acid acts as a depressant, slowing down the central nervous system. It is a precursor to GABA, a neurotransmitter that inhibits the activity of neurons. This can lead to effects such as relaxation, euphoria, and increased sociability. However, high doses can cause unconsciousness, seizures, and even death.

Medical use

Γ-Hydroxyvaleric acid is used in some countries as a treatment for narcolepsy, a sleep disorder characterized by excessive daytime sleepiness and sudden attacks of sleep. It can also be used to treat alcohol withdrawal symptoms.

Recreational use

As a recreational drug, Γ-Hydroxyvaleric acid is often used for its euphoric and sedative effects. It is also popular among bodybuilders, as it is believed to stimulate the release of growth hormone.

Legal status

The legal status of Γ-Hydroxyvaleric acid varies by country. In some places, it is a controlled substance, while in others it is completely illegal.
