'''Estrone glucuronide''', or '''estrone-3-<small>D</small>-glucuronide''', is a [[conjugation (biochemistry)|conjugated]] [[metabolite]] of [[estrone]].<ref name="HMDB">{{Cite web|url=http://www.hmdb.ca/metabolites/HMDB04483|title = Human Metabolome Database: Showing metabocard for Estrone glucuronide (HMDB0004483)}}</ref> It is formed from estrone in the [[liver]] by [[UDP-glucuronyltransferase]] via attachment of [[glucuronic acid]] and is eventually [[excretion|excreted]] in the [[urine]] by the [[kidney]]s.<ref name="HMDB" /> It has much higher [[water solubility]] than does estrone.<ref name="HMDB" /> Glucuronides are the most abundant estrogen conjugates and estrone glucuronide is the dominant metabolite of estradiol.<ref name="HMDB" />
