Metabolite Identification
Common NameHydroxykynurenine
DescriptionHydroxykynurenine, also known as hydroxykynurenine, belongs to the class of organic compounds known as alkyl-phenylketones. These are aromatic compounds containing a ketone substituted by one alkyl group, and a phenyl group. Hydroxykynurenine exists as a solid, possibly soluble (in water), and a very strong basic compound (based on its pKa) molecule. In cattle, hydroxykynurenine is involved in the metabolic pathway called the tryptophan metabolism pathway.
