title: The metabolism of 17beta-estradiol-3-glucosiduronate and estrone-3-glucosiduronate in the rabbit.
abstract: [6, 7-3H]-17beta-Estradiol-3-glucosiduronate, [6, 7-3H]-estrone-3-glucosiduronate or [6, 7-3H]-estrone was administered intravenously into the rabbit, and analysis and identification of the urinary metabolites were carried out. In either case, the major urinary metabolite was found to be a diconjugate. The sequential enzymic hydrolysis indicated that this diconjugate was glucosiduronate-N-acetyglucosaminide of 17alpha-estradiol. From these results, the conversion of the estrogen glucosiduronate into a diconjugate was thought a rather universal phenomenon in the rabbit.
