| | 17ALPHA-HYDROXYPREGNENOLONE Usage And Synthesis |
| Description | 17α-hydroxy Pregnenolone is a metabolite of pregnenolone and a precursor in the biosynthesis of dehydroepiandrosterone (DHEA; ). It is formed from pregnenolone by cytochrome P450 (CYP) isoform CYP17A1 hydroxylase activity and then converted to dehydroepiandrosterone by CYP17A1-mediated 17,20-lyase activity. Plasma levels of 17α-hydroxy pregnenolone are elevated in patients with type II 3β-hydroxysteroid dehydrogenase deficiency, a form of congenital adrenal hyperplasia. | | Uses | 17α-hydroxypregnenolone has been used as a substrate for the enzyme 3β‐hydroxysteroid dehydrogenase (3β‐HSD) expressed in COS1 cells. | | General Description | 17α-hydroxypregnenolone is a derived from pregnenolone. | | Biochem/physiol Actions | 17α-hydroxypregnenolone acts as a precursor for cortisol and sex steroids. |
