Description
3-Methyl-2-nitrophenol is a UDP-glucuronyltransferase (EC 2.4.1.17) acceptor substrate that can be confirmed to undergo glucuronidation catalyzed by the enzyme to form a glucuronide conjugate. 3-Methyl-2-nitrophenol functions as a substrate for conjugation, with glucuronidation forming a glucuronide conjugate that eliminates the parent compound’s characteristic yellow color. 3-Methyl-2-nitrophenol has higher lipid solubility that contributes to high glucuronidation conversion rate, and exhibits lower absorbance at 340 nm to act as a less interfering substrate for the NADH-NAD+-linked UDP-glucuronyltransferase assay[1]
