Triple

Target class: gamma-aminobutyric acid
Context triple: [GABA, instanceOf, gamma-aminobutyric acid]

• A. glutamate release inhibitor
  A glutamate release inhibitor is an agent that reduces the presynaptic release of the excitatory neurotransmitter glutamate, thereby modulating neuronal excitability and protecting against excitotoxicity.
• B. aromatic amino acid
  An aromatic amino acid is an amino acid whose side chain contains an aromatic ring, such as phenylalanine, tyrosine, or tryptophan, contributing to protein structure and function through hydrophobic interactions and π-π stacking.
• C. heterotrimeric G protein
  A heterotrimeric G protein is a membrane-associated signaling protein complex composed of three distinct subunits (α, β, and γ) that transduces signals from activated G protein–coupled receptors to intracellular effector pathways by cycling between GDP-bound inactive and GTP-bound active states.
• D. enaminol
  An enaminol is a tautomeric functional group featuring a carbon–carbon double bond adjacent to an amino group and a hydroxyl group on the same carbon, typically interconverting with its corresponding β-aminocarbonyl compound.
• E. G protein–coupled receptor
  A G protein–coupled receptor is a membrane-spanning protein that detects extracellular signals and activates intracellular G proteins to trigger specific cellular responses.
• F. None of above. chosen
