Metabolite Identification
Common Name4-Methoxycinnamic acid
Description4-Methoxycinnamic acid, also known as para-methoxycinnamate or O-methyl-p-coumarate, belongs to the class of organic compounds known as cinnamic acids. These are organic aromatic compounds containing a benzene and a carboxylic acid group forming 3-phenylprop-2-enoic acid. Outside of the human body, 4-Methoxycinnamic acid is found, on average, in the highest concentration within turmerics. 4-Methoxycinnamic acid has also been detected, but not quantified in cow milk and wild celeries. This could make 4-methoxycinnamic acid 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.
