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, an estrogen receptor agonist and a human urinary metabolite. It is a 16alpha-hydroxy steroid, a 17alpha-hydroxy steroid and a 3-hydroxy steroid. It derives from a hydride of an estrane.
