The Extraneural Distribution of γ‐Hydroxybutyrate

Abstract

gamma-Hydroxybutyrate has been found to be widely distributed in both neural and extraneural tissues in the rat. The kidney and brown fat have more than 10 times higher concentrations of gamma-hydroxybutyrate than does the brain. This observation suggests that gamma-hydroxybutyrate may participate in the metabolism of many organs, and that GABA may not be the precursor in extraneural tissues.
