Metabolite Identification
Common NameDihydrooroxylin
DescriptionDihydrooroxylin belongs to the class of organic compounds known as 6-o-methylated flavonoids. These are flavonoids with methoxy groups attached to the C6 atom of the flavonoid backbone. Thus, dihydrooroxylin is considered to be a flavonoid. Dihydrooroxylin has been detected, but not quantified in, fruits. This could make dihydrooroxylin a potential biomarker for the consumption of these foods. Dihydrooroxylin is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review a small amount of articles have been published on Dihydrooroxylin.

Enzymes

General function:
Involved in transferase activity, transferring hexosyl groups
Specific function:
UDPGT is of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds. This isoform glucuronidates bilirubin IX-alpha to form both the IX-alpha-C8 and IX-alpha-C12 monoconjugates and diconjugate. Is also able to catalyze the glucuronidation of 17beta-estradiol, 17alpha-ethinylestradiol, 1-hydroxypyrene, 4-methylumbelliferone, 1-naphthol, paranitrophenol, scopoletin, and umbelliferone.
