Metabolite Identification
Common Name18-Hydroxycortisol
Description18-Hydroxycortisol is a derivative of cortIsolated It may be synthesized by zona fasciculata 11-beta hydroxylase in normal human adrenal cortex. (PMID 15356073 ; 1751390) Overproduction of 18-hydroxycortisol is an aid in the detection of Glucocorticoid-remediable aldosteronism which is an inherited form of mineralocorticoid excess associated with moderate overproduction of aldosterone, in which biochemical and clinical remission is dramatically induced by small amounts of glucocorticoids.(PMID: 1879399 ).
