Metabolite Identification
Common NameBenzoin
DescriptionBenzoin, also known as PHCH(OH)COPH or benzoin tincture, belongs to the class of organic compounds known as benzoins. These are organic compounds containing a 1,2-hydroxy ketone attached to two phenyl groups. A ketone that consists of acetophenone bearing hydroxy and phenyl substituents at the alpha-position. Benzoin is an extremely weak basic (essentially neutral) compound (based on its pKa). Benzoin is a bitter, medicinal, and vanilla. Benzoin is a potentially toxic compound.

Enzymes

General function:
Involved in sulfotransferase activity
Specific function:
Sulfotransferase that utilizes 3'-phospho-5'-adenylyl sulfate (PAPS) as sulfonate donor to catalyze the sulfate conjugation of many hormones, neurotransmitters, drugs and xenobiotic compounds. Sulfonation increases the water solubility of most compounds, and therefore their renal excretion, but it can also result in bioactivation to form active metabolites. Sulfates hydroxysteroids like DHEA. Isoform 1 preferentially sulfonates cholesterol, and isoform 2 avidly sulfonates pregnenolone but not cholesterol.

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.
