Hydroxysteroid dehydrogenase

From Wikipedia, the free encyclopedia

Hydroxysteroid dehydrogenase is a type of alcohol oxidoreductases which acts as a dehydrogenase upon a hydroxysteroid.

There are four types, classified by the number of the carbon acted upon:

Carbon	From	To
3	pregnenolone	progesterone
3	17-Hydroxypregnenolone	17-Hydroxyprogesterone
3	dehydroepiandrosterone	androstenedione
11	cortisol	cortisone
17	androstenedione	testosterone
20	progesterone	20-alpha-dihydroprogesterone
