Gamma-aminobutyric acid
Gamma-aminobutyric acid (GABA) is a non-protein amino acid
that acts as the main inhibitory neurotransmitter in the mammalian
cortex since it was first discovered as an integral part of
the mammalian central nervous system. It was discovered in plants
half a century ago and synthesized through a metabolic pathway
called the ‘GABA shunt’. The formation and bio-functions of GABA
have been extensively studied. According to previous reports,
GABA synthesis could be elevated by environmental stress,
