Natural Product Identification
Common Name5a-Tetrahydrocorticosterone
Description5A-Tetrahydrocorticosterone, also known as allothb, 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, 5a-tetrahydrocorticosterone is considered to be a steroid lipid molecule. 5a-Tetrahydrocorticosterone was first documented in 1995 (PMID: 7473516). 5A-Tetrahydrocorticosterone is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral (PMID: 16597193).
