Quercetin
Quercetin is a plant flavonol from the flavonoid group of polyphenols. It is found in many fruits, vegetables, leaves, seeds, and grains; capers, red onions, and kale are common foods containing appreciable amounts of it. It has a bitter flavor and is used as an ingredient in dietary supplements, beverages, and foods. Occurrence Quercetin is a flavonoid widely distributed in nature. The name has been used since 1857, and is derived from ''quercetum'' (oak forest), after the oak genus ''Quercus''. It is a naturally occurring polar auxin transport inhibitor. Quercetin is one of the most abundant dietary flavonoids, with an average daily consumption of 25–50 milligrams. In red onions, higher concentrations of quercetin occur in the outermost rings and in the part closest to the root, the latter being the part of the plant with the highest concentration. One study found that organically grown tomatoes had 79% more quercetin than non-organically grown fruit. Quercetin is presen ...

Sulfate Conjugate
Sulfate conjugates are a heterogeneous class of polar, anionic organosulfate compounds containing an ester of sulfuric acid. Sulfate conjugates commonly result from the metabolic conjugation of endogenous and exogenous compounds with sulfate (-OSO3−). Biosynthesis of sulfate esters requires an activated sulfate donor, usually adenosine 5'-phosphosulfate (APS) or 3'-phosphoadenosine-5'-phosphosulfate (PAPS).M. T. Madigan, J. M. Martinko, J.

Adenosine 3',5'-bisphosphate
Adenosine 3',5'-bisphosphate is a form of an adenosine nucleotide with two phosphate groups attached to different carbons in the ribose ring. This is distinct from adenosine diphosphate, where the two phosphate groups are attached in a chain to the 5' carbon atom in the ring. Adenosine 3',5'-bisphosphate is produced as a product of sulfotransferase enzymes from the donation of a sulfate group from the coenzyme 3'-phosphoadenosine-5'-phosphosulfate. This product is then hydrolysed by 3'(2'),5'-bisphosphate nucleotidase to give adenosine monophosphate, which can then be recycled into adenosine triphosphate.
