Common Name | 3a,21-Dihydroxy-5b-pregnane-11,20-dione |
---|
Description | 3alpha,21-Dihydroxy-5beta-pregnane-11,20-dione is an intermediate in C21-Steroid hormone metabolism. 3alpha,21-Dihydroxy-5beta-pregnane-11,20-dione is converted from Tetrahydrocorticosterone via the enzyme 11beta-hydroxysteroid dehydrogenase (EC 1.1.1.146). It is then converted to 3alpha,20alpha,21-Trihydroxy-5beta-pregnane-11-one via the enzyme 3alpha(or 20beta)-hydroxysteroid dehydrogenase (EC 1.1.1.53). |
