Common Namep-Ethylphenol
Description4-Ethylphenol, 4-EP or p-Ethylphenol is an ethylated derivative of phenol. It belongs to the class of organic compounds known as 1-hydroxy-2-unsubstituted benzenoids. These are phenols that are unsubstituted at the 2-position. 4-Ethylphenol is one of three structural isomers of ethylphenol wherein the ethyl group is substituted at three positions of phenol (the ortho, meta and para positions). 4-Ethylphenol is also classified as an alcohol. It exists as a white solid that is weakly soluble in water. It has a smoky, phenolic, guaiacol odor and a smoky, bacon or ham flavor. It is used in the cosmetic industry as a perfuming agent. 4-Ethylphenol exists in all living species, ranging from bacteria to plants to humans. 4-Ethylphenol has been detected, but not quantified in, several different plants, foods and beverages such as arabica coffee, wine, beers, cottage cheese, corn, cranberries, fish, pork, milk, wine and red raspberries. This could make 4-ethylphenol a potential biomarker for the consumption of these foods. 4-Ethylphenol is produced in wine and beer by the yeast Brettanomyces. In wines 4-EP is generally undesirable while in certain Belian beers, it can be desirable. 4-Ethylphenol at the concentration of 140 µg/L gives wines a barnyard, medicinal, or mousy aroma. In plants and yeast, 4-EP is produced from the precursor p-coumaric acid. This is converted to 4-vinylphenol via the enzyme cinnamate decarboxylase which is further reduced to 4-Ethylphenol by the enzyme vinyl phenol reductase. At high doses, 4-Ethylphenol is a potentially toxic compound. 4-Ethylphenol poisoning can lead to respiratory distress, cardiovascular collapse, shock, ventricular tachycardia, and coma. Liver, lung, central nervous system and renal injury may also occur. Systemic manifestations of toxicity may include nausea, vomiting, diarrhea, dyspnea, tachypnea, pallor, and profuse sweating. p-Ethylphenol is one of several phenolic compounds found in cannabis smoke and is formed during the combustion of cannabis ( Ref:DOI ).

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.
