Metabolite Identification
Common Name4'-O-Methylglabridin
Description4'-O-Methylglabridin belongs to the class of organic compounds known as pyranoisoflavonoids. These are isoflavonoids that contain a pyran ring fused to either of the A, B, or C ring of the isoflavonoid skeleton. Thus, 4'-O-methylglabridin is considered to be a flavonoid. 4'-O-Methylglabridin has been detected, but not quantified in, several different foods, such as green tea, teas (Camellia sinensis), herbs and spices, herbal tea, and red tea. This could make 4'-O-methylglabridin a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 4'-O-Methylglabridin.

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.
