Cortisol binding globulin and cortisol levels
WebTetrahydrocortisol is a metabolite of cortisol. Cortisol is metabolized into 5-alphaTetrahydrocortisol (5a-THF) and 5-beta-Tetrahydrocortisol (5b-THF). These will often reflect a chronic adrenal picture if levels are out of normal limits. Urine contains free cortisol, but it also contains many cortisol metabolites, like cortisone or 5-alpha ... WebCorticosteroid-binding globulin has been known since 1956 as a plasma protein capable of high-affinity interaction with cortisol ( 4 ). It was purified in the early 60s and cloned and characterized since the 90s in many species ( 7 ). Recently, CBG has been identified as a major component of GC genetic variability in animals and humans.
