Metabolite Identification
Common NameAesculetin
DescriptionAesculetin, also known as cichorigenin or cichoriin aglucon, belongs to the class of organic compounds known as 6,7-dihydroxycoumarins. These are coumarins bearing two hydroxyl groups at positions 6 and 7 of the coumarin skeleton, respectively. Aesculetin is found, on average, in the highest concentration within sherries. Aesculetin has also been detected, but not quantified, in several different foods, such as horseradish, carrots, dandelions, grape wines, and highbush blueberries. This could make aesculetin a potential biomarker for the consumption of these foods.

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.
