Nicotine
glucuronide (nicotine) accounts for 3-5% of the converted nicotine, and in the human body, before it is excreted in the urine, nicotine is modified by the catalyst uridine diphosphate-glucuronic acid glycosyl transferase (UGT).
Identification of b-glucuronidase-resistant diastereomeric
glucuronides of 3-hydroxy-3methyloxindole formed during 3-methylindole metabolism in goats.
The inactivation pathway occurs mainly in the liver via conjugation into testosterone conjugates (
glucuronides and to a lesser extent sulfates) and in equal proportions into the 17-ketosteroids (androsterone and etiocholanolone).
Biotransformation of bisphenol AF to its major
glucuronide metabolite reduces estrogenic activity.
In order to ensure that the drugs are completely liberated from their
glucuronide, careful selection of the hydrolysis control is necessary.
The serum and urine samples were previously analyzed for their content in the 6 unconjugated precursors of the
glucuronide derivatives analyzed here [20].
Compounds 1 and 2 are glucosides, 3 and 4 are methoxy aglycones, compounds 5 and 6 are
glucuronides, and compounds 8-10 are aglycones.
Stability of mycophenolic acid and
glucuronide metabolites in human plasma and the impact of deproteinization methodology.
Detection of the direct alcohol biomarker ethyl
glucuronide (EtG) in hair: an annotated bibliography, http://www.usdtl.com/media/ white-papers/ETG_hair_annotated_bibliography_032014.
T/E test (testosterone/epitestosterone
glucuronide) is another test, but also limited by the timing of the test.
However, all of the retention times of the materials conformed to their standard carves, indicating that there was also a slight amount of the parent resveratrol-3-O-glucuronide and resveratrol-4'-O-
glucuronide in the vitreous humor.
