3-Hydroxykynurenine is a metabolite of tryptophan, which filters UV light in the human lens.[1] It is one of two pigments identified as responsible for the goldenrod crab spider's (Misumena vatia) yellow coloration.

The Kynurenine pathway, which connects quinolinic acid to tryptophan. The pathway is named for the first intermediate, kynurenine, which is a precursor to kynurenic acid and 3-hydroxykynurenine.[2]
