FooDB Name | 17alpha,20alpha-Dihydroxycholesterol |
---|
Description | 17alpha,21-Dihydroxypregnenolone, also known as 3β,17,21-trihydroxy-pregn-5-en-20-one, belongs to the class of organic compounds known as 21-hydroxysteroids. These are steroids carrying a hydroxyl group at the 21-position of the steroid backbone. Thus, 17alpha,21-dihydroxypregnenolone is considered to be a steroid lipid molecule. 17alpha,21-Dihydroxypregnenolone is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. |
