HOOCCH2CH2CH2NH2
HOOC-CH2-CH2-CH2-NH2 is the structural representation of gamma-aminobutyric acid (GABA), a four-carbon molecule with a carboxyl group on one end and an amino group on the other. Its IUPAC name is 4-aminobutanoic acid, and its molecular formula is C4H9NO2. In physiological conditions it exists mainly as a zwitterion, with a deprotonated carboxylate and a protonated amine, making it a polar compound that does not readily cross the blood–brain barrier in its neutral form.
Biological role and metabolism: GABA is the principal inhibitory neurotransmitter in the vertebrate central nervous system,
Receptors and pharmacology: GABA exerts its effects through GABA receptors, including GABA-A (ligand-gated chloride channel) and
Applications: Beyond its role as a neurotransmitter, GABA and its derivatives serve as research tools and chemical
