where does the conversion of a prohormone into a hormone take place
Hormone To release active hormones quickly into the circulation, hormone biosynthetic cells may produce and store biologically inactive hormones in the form of pre- or prohormones. These can then be quickly converted into their active hormone form in response to a particular stimulus.
Percy Lavon Julian Percy Lavon Julian (April 11, 1899 â€“ April 19, 1975) was an African American research chemist and a pioneer in the chemical synthesis of medicinal drugs from plants.[1] He was the first to synthesize the natural product physostigmine, and a pioneer in the industrial large-scale chemical synthesis of the human hormones progesterone and testosterone from plant sterols such as stigmasterol and sitosterol. His work laid the foundation for the steroid drug industry's production of cortisone, other corticosteroids, and birth control pills.[2][3][4]
