5β-Androstan-3α-ol-17-one-[d5] (Etiocholanolone-d5)

5β-Androstan-3α-ol-17-one-[d5], also known as Etiocholanolone-d5, is a deuterated form of etiocholanolone, a steroid hormone found in urine and blood. This compound is commonly used in research and medical fields to study the metabolism and excretion of steroids in humans and animals. Etiocholanolone-d5 is a stable isotope-labeled compound, meaning that it contains five deuterium atoms in place of five hydrogen atoms. This alteration in the molecular structure allows for accurate tracking and measurement of the compound's movement and effects in biological systems. In research, Etiocholanolone-d5 is used as an internal standard in mass spectrometry and gas chromatography to quantify the levels of etiocholanolone in biological samples. It is also used in clinical studies to investigate the role of etiocholanolone in conditions such as adrenal insufficiency and androgen deficiency. Chemically, Etiocholanolone-d5 is a derivative of testosterone and dihydrotestosterone, two hormones known for their anabolic effects on muscle growth and strength. However, etiocholanolone and its deuterated form do not possess these anabolic properties and are instead primarily involved in the metabolism and excretion of other steroid hormones. Overall, Etiocholanolone-d5 is a valuable tool in steroid research and medical diagnostics, providing accurate and reliable measurements of etiocholanolone levels in biological samples.
