Metabolite Identification
Common NameTetrahydrocortisol
DescriptionTetrahydrocortisol, also known as dihydrocortison or urocortisol, 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. Tetrahydrocortisol is considered to be a practically insoluble (in water) and relatively neutral molecule. Tetrahydrocortisol has been found in human hepatic tissue tissue, and has also been primarily detected in urine. Within the cell, tetrahydrocortisol is primarily located in the membrane (predicted from logP) and cytoplasm. Tetrahydrocortisol can be converted into dihydrocortisol; which is mediated by the enzyme aldo-keto reductase family 1 member C4. In humans, tetrahydrocortisol is involved in the steroidogenesis pathway. Tetrahydrocortisol is also involved in several metabolic disorders, some of which include adrenal hyperplasia type 3 or congenital adrenal hyperplasia due to 21-hydroxylase deficiency, adrenal hyperplasia type 5 or congenital adrenal hyperplasia due to 17 Alpha-hydroxylase deficiency, 17-alpha-hydroxylase deficiency (cyp17), and corticosterone methyl oxidase II deficiency - cmo II.

General function:
Involved in oxidoreductase activity
Specific function:
Catalyzes the transformation of the potent androgen dihydrotestosterone (DHT) into the less active form, 5-alpha-androstan-3-alpha,17-beta-diol (3-alpha-diol). Also has some 20-alpha-hydroxysteroid dehydrogenase activity. The biotransformation of the pesticide chlordecone (kepone) to its corresponding alcohol leads to increased biliary excretion of the pesticide and concomitant reduction of its neurotoxicity since bile is the major excretory route.
