Estrone Sulfate, Estrone, Estradiol and Estriol Plasma Levels in Human Pregnancy
The Journal of Clinical Endocrinology & Metabolism, 1972ABSTRACT Estrone sulfate, estrone, estradiol and estriol were measured through the course of pregnancy in 85 women. Of the unconjugated estrogens, estradiol had the highest plasma concentration, being approximately twice that of estrone and four times that of estriol. Estrone sulfate level was twice that of estradiol.

Enterohepatic cycling of 3H-estrone in the bull: Identification of estrone-3-glucuronide
Journal of Steroid Biochemistry, 1975Abstract Following surgical preparation of a bull with indwelling catheters in the gallbladder and duodenum, the animal was injected with radio-estrone. Bile was collected. Subsequently, this bile containing radioactive metabolites, all of which appeared to be conjugated with glucuronic acid, was infused into the duodenum.

Chiral Hydrogenation of Estrone and Estrone-3-Methyl Ether
1995We have previously studied the use of enantiomeric chiral reducing agents in solution to control the direction of the hydrogenation of the keto group of estrone and estrone-3-methyl ether [1]. The complex catalysts chiral hydrosilane-rhodium-( +)- or (-)-DIOP or (+)- or (-)-BINAP allowed different stereoselectivities in the formation of the 17α- and ...

In the rat, estrone sulphate is the main serum metabolite of oral oleoyl-estrone
Journal of Endocrinological Investigation, 2007Two different oral doses of oleoyl-estrone: 1 and 10 nmol/g a day were given once to male Wistar rats. The serum levels of free estrone, estrone sulphate, estradiol, and acyl-estrone were measured at intervals up to 72 h after the gavage. Oleoyl-estrone was rapidly absorbed; with the 1 nmol/g dose no changes were observed in plasma acyl-estrone but ...

Conversion of estrone to estradiol and estradiol to estrone in postmenopausal women.
Obstetrics and gynecology, 1985The conversion of estrone to estradiol and metabolism of estradiol to estrone have been measured in postmenopausal women to examine factors that influence these conversions. Transfer constants for the conversion of estrone to estradiol and estradiol to estrone were not significantly correlated with age (r = -.01 and r = .1, respectively) or subjects ...

Estrone sulphate and estrone splanchnic extraction in postmenopausal women.
Acta Europaea fertilitatis, 1983The splanchnic extraction of estrone sulphate (E1 S) and estrone (E1) was calculated in post-menopausal women undergoing cardiac catheterization for diagnostic purposes. The results showed a net uptake for E1 by the splanchnic area, liver included, whereas the splanchnic extraction of E1 S was not similar for each subject.
