Natural Product Identification
Common Name18-Hydroxycortisol
Description18-Hydroxycortisol 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, 18-hydroxycortisol is considered to be a steroid lipid molecule. 18-Hydroxycortisol was first documented in 1985 (PMID: 3002670). 18-Hydroxycortisol is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral (PMID: 1567095) (PMID: 3995762) (PMID: 8001289) (PMID: 15356073) (PMID: 1879399).
