glucuronidation

glucuronidation (glōō·k·rō·n·dāˑ·shn),

n a phase II detoxification pathway occurring in the liver in which glucuronic acid is conjugated with toxins. Effectively detoxifies the majority of commonly prescribed drugs.

Detox mechanisms include acetylation, sulfating, glucuronidation, and oxidation.
Direct analysis of intact conjugates was a prerequisite for assessing the impact of glucuronidation and sulfation of MDMA's phase I metabolites.
17[alpha]-Ethinylestradiol is mainly metabolized via intestinal and hepatic oxidation (CYP3A4), glucuronidation (UGT1A1) and sulfation (SULTs) (Zhang et al.
Although both adult rodents and primates use glucuronidation of BPA through uridine 5 '-diphospho-glucuronosyltransferases as part of their phase II metabolism system, the primary mechanism through which BPA is cleared from blood differs, with urinary excretion being the primary route in primates versus the biliary--fecal route in rodents (Inoue et al.
BPA is metabolized in the liver by the CYP450 enzymes, and methylation and glucuronidation.
Metabolism creates about 40 metabolites via multiple metabolic pathways; the main ones are glucuronidation by UGT1A4 and oxidative metabolism by cytochrome P450 (CYP)1A2.
The reactions examined here include methylation, sulfation, glucuronidation, acetylation, conjugation with glutathione, while there is also a rigorous presentation of the pivotal role of xenobiotic-coenzyme A conjugates as a crossroads to various metabolic reactions.
In pharmacokinetic aspect, VPA is metabolized primarily by direct glucuronidation to form the acyl glucuronide (VPA-G) and also by [beta]-oxidation (Davis et al.
UDP-glucuronosyltransferases (UGTs) [4] are important enzymes involved in the glucuronidation of diverse exogenous and endogenous compounds.
