Metabolite Identification
Common NameKaempferol
DescriptionKaempferol, also known as rhamnolutein or c.i. 75640, belongs to the class of organic compounds known as flavonols. Flavonols are compounds that contain a flavone (2-phenyl-1-benzopyran-4-one) backbone carrying a hydroxyl group at the 3-position. Thus, kaempferol is considered to be a flavonoid molecule. A tetrahydroxyflavone in which the four hydroxy groups are located at positions 3, 5, 7 and 4'. Kaempferol is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. Kaempferol exists in all eukaryotes, ranging from yeast to humans. Kaempferol is a bitter tasting compound. Kaempferol is found, on average, in the highest concentration within a few different foods, such as saffrons, capers, and cumins and in a lower concentration in lovages, endives, and cloves. Kaempferol has also been detected, but not quantified, in several different foods, such as shallots, pine nuts, feijoa, kombus, and chicory leaves. This could make kaempferol a potential biomarker for the consumption of these foods. Kaempferol is a potentially toxic compound.

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.
