Common NameDihydrocortisol
DescriptionDihydrocortisol 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, dihydrocortisol is considered to be a steroid lipid molecule. Dihydrocortisol is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Within humans, dihydrocortisol participates in a number of enzymatic reactions. In particular, dihydrocortisol can be converted into cortisol through its interaction with the enzyme 3-oxo-5-beta-steroid 4-dehydrogenase. In addition, dihydrocortisol can be biosynthesized from tetrahydrocortisol through its interaction with the enzyme aldo-keto reductase family 1 member C4. In humans, dihydrocortisol is involved in the metabolic disorder called the 11-beta-hydroxylase deficiency (cyp11b1) pathway. Dihydrocortisol was first documented in 1983 (PMID: 6821952). A 17alpha-hydroxy-C21-steroid that is cortisol in which the 4-5 double bond has undergone formal hydrogenation to give the corresponding 5beta- steroid (PMID: 10543414) (PMID: 11585134) (PMID: 29375009) (PMID: 3793407).
