| Common Name | 5-Hydroxykynurenine |
|---|
| Description | 5-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. A hydroxykynurenine that is kynurenine bearing a hydroxy group at the position 5. 5-Hydroxykynurenine is a very strong basic compound (based on its pKa). Within humans, 5-hydroxykynurenine participates in a number of enzymatic reactions. In particular, 5-hydroxykynurenine and formic acid can be biosynthesized from 5-hydroxy-N-formylkynurenine; which is mediated by the enzyme kynurenine formamidase. In addition, 5-hydroxykynurenine can be converted into 5-hydroxykynurenamine; which is mediated by the enzyme aromatic-L-amino-acid decarboxylase. In humans, 5-hydroxykynurenine is involved in tryptophan metabolism. |
