Metabolite Identification
Common NameRepensol
DescriptionRepensol belongs to the class of organic compounds known as coumestans. These are polycyclic aromatic compounds containing a coumestan moiety, which consists of a benzoxole fused to a chromen-2-one to form 1-Benzoxolo[3,2-c]chromen-6-one. They are oxidation products of pterocarpan. Thus, repensol is considered to be a flavonoid lipid molecule. Repensol is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Outside of the human body, repensol has been detected, but not quantified in, a few different foods, such as green vegetables, herbs and spices, and tea. This could make repensol a potential biomarker for the consumption of these foods.

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.
