化合物简介
20β-Dihydrocortisol could be used as a potential non invasive diagnostic test of transmissible spongiform encephalopaties. 20β-Dihydrocortisol is a metabolite of Cortisol, a steroid hormone, more specifically a glucocorticoid, produced by the zona fasciculata of the adrenal gland. Cortisol is released in response to stress and a low level of blood glucocorticoids. Its primary functions are to increase blood sugar through gluconeogenesis; suppress the immune system; and aid in fat, protein and carbohydrate metabolism.
