Pregnanediol 3-O-glucuronide is a natural human metabolite of pregnanediol generated in the liver by UDP glucuronyltransferase. Glucuronidation is used to assist in the excretion of toxic substances, drugs, or other substances that cannot be used as an energy source. Glucuronic acid is attached via a glycosidic bond to the substance, and the resulting glucuronide, which has a much higher water solubility than the original substance, is eventually excreted by the kidneys. Pregnanediol 3-O-glucuronide has been identified in the human placenta (PMID: 32033212). Pregnanediol-3-glucuronide is a natural human metabolite of Pregnanediol generated in the liver by UDP glucuonyltransferase.
