Common Name

4,7-Dihydroxy-2H-1-benzopyran-2-one

Description

4,7-Dihydroxy-2H-1-benzopyran-2-one belongs to the class of organic compounds known as 7-hydroxycoumarins. These are coumarins that contain one or more hydroxyl groups attached to the C7 position the coumarin skeleton. 4,7-Dihydroxy-2H-1-benzopyran-2-one has been detected, but not quantified in, several different foods, such as red tea, green vegetables, teas (Camellia sinensis), black tea, and herbs and spices. This could make 4,7-dihydroxy-2H-1-benzopyran-2-one a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 4,7-Dihydroxy-2H-1-benzopyran-2-one.

Enzyme Details

1. UDP-glucuronosyltransferase 1-1

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.
Gene Name:: UGT1A1
Uniprot ID:: P22309
Molecular weight:: 59590.91
