Common NameEpicatechin-(4beta->6)-epicatechin-(2beta->7,4beta->8)-epicatechin
DescriptionEpicatechin-(4beta->6)-epicatechin-(2beta->7,4beta->8)-epicatechin belongs to the class of organic compounds known as biflavonoids and polyflavonoids. These are organic compounds containing at least two flavan/flavone units. These units are usually linked through CC or C-O-C bonds. Some examples include C2-O-C3, C2-O-C4, C3'-C3''', and C6-C8''. Epicatechin-(4beta->6)-epicatechin-(2beta->7,4beta->8)-epicatechin is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, epicatechin-(4beta->6)-epicatechin-(2beta->7,4beta->8)-epicatechin has been detected, but not quantified in, fruits. This could make epicatechin-(4beta->6)-epicatechin-(2beta->7,4beta->8)-epicatechin a potential biomarker for the consumption of these foods.

Enzymes

General function:
Involved in magnesium ion binding
Specific function:
Catalyzes the O-methylation, and thereby the inactivation, of catecholamine neurotransmitters and catechol hormones. Also shortens the biological half-lives of certain neuroactive drugs, like L-DOPA, alpha-methyl DOPA and isoproterenol.

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.
