• Androstanes
  • Androstanes are more polar than androstenes , and hence are hygroscopic and water soluble (this is inherently interrelated to increased efficacy at receptor sites via increased membrane permeability ). (alpha-dream.com)
  • Catalyzes the conversion of the 17-keto group of estrone, 4- and 5-androstenes and 5-alpha-androstanes into their 17-beta-hydroxyl metabolites and the conversion of the 3-keto group of 3-, 3,17- and 3,20- diketosteroids into their 3-hydroxyl metabolites. (nih.gov)
