20α-Acetoxy-5β-pregnan-3α-ol is the unlabeled form of 20α-Acetoxy-5β-pregnan-3α-ol-d5 (A165152), which is an intermediate in synthesizing Pregnanediol-d5 3α-O-β-D-Glucuronide (P705142), which is a glucuronide conjugate of Pregnanediol (P705130). Levels of Pregnanediol 3α-O-β-D-Glucuronide can be used to monitor the reproductive status of dairy cows. 3α-O-β-D-Glucuronide can be used (as an alternative to creatine) as a reference to adjust other hormonal markers in study of urinary hormonal profiles in the human menstrual cycle.
