An estrogenic metabolite of estradiol, usually the predominant estrogenic metabolite found in urine (especially during pregnancy); epimers at C-16, C-17, or both, are known as 16-epiestriol, 16,17-epiestriol, and 17-epiestriol.
estriol/es·tri·ol/ (es´tre-ol) a relatively weak human estrogen (q.v.), being a metabolic product of estradiol and estrone found in high concentrations in urine, especially during pregnancy.
estriol(ĕs′trī-ôl′, -ōl′, -ŏl′, ĕ-strī′-)
An estrogenic hormone, C18H24O3, that is a metabolite of estradiol and is present chiefly during pregnancy. It is produced by the placenta and is found in the urine of pregnant women.
a relatively weak, naturally occurring human estrogen found in high concentrations in urine. Also spelled oestriol. See also estrogen.
