Phrase: kynurenine pathway | Statement: [tryptophan, participatesInPathway, kynurenine pathway]

Target entity: kynurenine pathway
Context triple: [tryptophan, participatesInPathway, kynurenine pathway]

• A. Ketoy
  Ketoy is an uninhabited volcanic island in the central Kuril Islands chain in the northwest Pacific Ocean.
• B. Metabolism
  Metabolism was a postwar Japanese architectural movement that envisioned cities and buildings as dynamic, organic systems capable of continuous growth and change through modular, flexible design.
• C. essential amino acid tryptophan
  Essential amino acid tryptophan is a vital nutrient that humans must obtain from their diet and that serves as a biochemical precursor to important molecules such as serotonin, melatonin, and niacin.
• D. endocannabinoid system
  The endocannabinoid system is a widespread cell-signaling network in the body that helps regulate processes such as mood, appetite, pain, memory, and immune function through cannabinoid receptors, endogenous ligands, and metabolic enzymes.
• E. substantia nigra
  The substantia nigra is a midbrain structure rich in dopamine-producing neurons that plays a key role in movement control and is critically involved in Parkinson’s disease.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
