Metabolite Identification
Common NameIsosilychristin
DescriptionIsosilychristin belongs to the class of organic compounds known as 2-arylbenzofuran flavonoids. These are phenylpropanoids containing the 2-phenylbenzofuran moiety. Isosilychristin has been detected, but not quantified in, several different foods, such as arabica coffees (Coffea arabica), coffee and coffee products, green vegetables, and robusta coffees (Coffea canephora). This could make isosilychristin a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on Isosilychristin.

Enzymes

General function:
Involved in sulfotransferase activity
Specific function:
Sulfotransferase that utilizes 3'-phospho-5'-adenylyl sulfate (PAPS) as sulfonate donor to catalyze the sulfate conjugation of many hormones, neurotransmitters, drugs and xenobiotic compounds. Sulfonation increases the water solubility of most compounds, and therefore their renal excretion, but it can also result in bioactivation to form active metabolites. Sulfates hydroxysteroids like DHEA. Isoform 1 preferentially sulfonates cholesterol, and isoform 2 avidly sulfonates pregnenolone but not cholesterol.

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.
