17-Epiestriol (Estriol EP Impurity E) is a metabolite of Estradiol. | [Uses]
A metabolite of Estradiol | [Definition]
ChEBI: 17-epiestriol is a 16alpha-hydroxy steroid that is estriol in which the hydroxy group at position 17 has been epimersied from beta- to alpha- configuration. It is a metabolite of estradiol and a selective estrogen receptor beta (ER-beta) agonist. It has a role as an estrogen receptor agonist, a human urinary metabolite and an estrogen. It is a 16alpha-hydroxy steroid, a 17alpha-hydroxy steroid and a 3-hydroxy steroid. It derives from a hydride of an estrane. | [Biochem/physiol Actions]
17-epiestriol is an estradiol metabolite and a selective estrogen receptor (ER) beta agonist. |
