3-羟基犬尿氨酸

Also known as 3-(3-hydroxyanthraniloyl)alanine, 2-amino-4-(2-amino-3-hydroxyphenyl)-4-oxobutanoic acid, 3-Hydroxy-DL-kynurenine, 3-Hydroxykynurenine, 3-(3-Hydroxyanthraniloyl)-Alanine, DL-3-Hydroxykynurenine, Hydroxykinurenine, 3-Hydroxy-Kynurenine

3-Hydroxykynurenine is a metabolite of tryptophan, which filters UV light in the human lens. It is one of two pigments identified as responsible for the goldenrod crab spider's (Misumena vatia) yellow coloration. thumb|280px|left|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.]]
