GABA
GABA
GABA (Gamma-Aminobutyric Acid), pronounced as /ˈɡæbə/, is a naturally occurring amino acid that works as a neurotransmitter in your brain.
Etymology
The term GABA stands for Gamma-Aminobutyric Acid. It was first discovered in 1950 by Eugene Roberts and J. Awapara. The name is derived from its chemical structure, which consists of an amino group (NH2) and a carboxyl group (COOH) attached to a butyric acid molecule.
Function
GABA is considered an inhibitory neurotransmitter because it blocks, or inhibits, certain brain signals and decreases activity in your nervous system. When GABA attaches to a protein in your brain known as a GABA receptor, it produces a calming effect. This can help with feelings of anxiety, stress, and fear.
