Metabolite Identification
Common Name4-Ethylphenol
Description4-Ethylphenol belongs to the class of organic compounds known as 1-hydroxy-4-alkyl benzenoids. These are phenols that are substituted by an alkyl group at the para-position. 4-Ethylphenol exists in all living species, ranging from bacteria to humans. 4-Ethylphenol is an alcohol tasting compound. 4-Ethylphenol has been detected, but not quantified, in several different foods, such as arabica coffee, beers, corns, milk (cow), and red raspberries. 4-Ethylphenol is a potentially toxic compound, capable of producing respiratory distress, cardiovascular collapse, shock, ventricular tachycardia, and coma in an adult. Liver, lung, central nervous system and renal injury may also occur. In case of exposure to eyes, irrigate exposed eyes with copious amounts of room temperature water for at least 15 minutes. Monitor for respiratory distress in case of inhalation exposure. Systemic manifestations of toxicity may include nausea, vomiting, diarrhea, dyspnea, tachypnea, pallor, and profuse sweating.

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.
