Description

Application

For the introduction of 3-carboxypropyl side chain. Used as a component of electrolyte solutions in batteries and capacitors.

Biochem/physiol Actions

Precursor of γ-hydroxybutyric acid (GHB). It blocks dopamine release by blocking impulse flow in dopaminergic neurons. Pretreatment with γ-butyrolactone allows detection of autoreceptor-induced dopamine release.
