Common Name 3a-Hydroxy-5b-pregnane-20-one
Description 3alpha-Hydroxy-5beta-pregnane-20-one is an intermediate in C21-Steroid hormone metabolism. 3alpha-Hydroxy-5beta-pregnane-20-one is converted from 5beta-Pregnane-3,20-dione via the enzyme 3-alpha-hydroxysteroid dehydrogenase (EC 1.1.1.50). It is then converted to Pregnanediol via the enzyme 3alpha(or 20beta)-hydroxysteroid dehydrogenase (EC 1.1.1.53).

Enzyme 1 General Function Not Available
Enzyme 1 Specific Function Catalyzes the transformation of the potent androgen dihydrotestosterone (DHT) into the less active form, 5-alpha- androstan-3alpha,17beta-diol (3-alpha-diol). Also has some 20- alpha-hydroxysteroid dehydrogenase activity. The biotransformation of the pesticide chlordecone (kepone) to its corresponding alcohol leads to increased biliary excretion of the pesticide and concomitant reduction of its neurotoxicity since bile is the major excretory route
