Metabolite Identification
Common Namem-Coumaric acid
Descriptionm-Coumaric acid, also known as 3-coumarate, belongs to the class of organic compounds known as hydroxycinnamic acids. Hydroxycinnamic acids are compounds containing an cinnamic acid where the benzene ring is hydroxylated. m-Coumaric acid exists in all living organisms, ranging from bacteria to humans. m-Coumaric acid (CAS: 588-30-7) is a polyphenol metabolite from caffeic acid, formed by the gut microflora. Outside of the human body, m-Coumaric acid is found, on average, in the highest concentration within a few different foods, such as olives, corns, and beers. m-Coumaric acid has also been detected, but not quantified in several different foods, such as carrots, strawberries, grape wines, garden tomato, and bilberries. MCT-mediated absorption of phenolic compounds per se and their colonic metabolites would exert a significant impact on human health (PMID:16870009 , 15479001 , 15479001 ). m-Coumaric acid is transported by the monocarboxylic acid transporter (MCT). The amount of this compound in human biofluids is diet-dependant. m-Coumaric acid is detected after the consumption of whole grain.

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.
