(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 .
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.
