Mineralocorticoid biosynthesis (R-HSA-193993) [Homo sapiens]


Aldosterone, the major human mineralocorticoid, is synthesized in the zona glomerulosa of the adrenal cortex from pregnenolone. Pregnenolone is converted to progesterone in two reactions, both catalyzed by 3-beta-hydroxysteroid dehydrogenase/isomerase. Progesterone is hydroxylated by CYP21A2 to form deoxycorticosterone, which in turn is converted to aldosterone in a three-reaction sequence catalyzed by CYP11B2 (Payne and Hales 2004).
