[Paths of corticosteroid biosynthesis in the adrenal glands of rhesus monkeys].
In experiments in vitro corticosteroid formation from radioactive cholesterol in tha adrenal glands of monkeys (Macaca rhesus) was studied. A conclusion was drawn that pregnenolone and its hydroxy-derivatives were of the leading significance in the cortizol and corticosterone synthesis in the adrenal glands of monkeys. Progesteron was produced in insignificant amounts and was almost unutilized for steroidogenesis. The formation of 17.21-dioxypregnenolone was revealed; its role in the capacity of cortizol precursor was proved; 17-oryprogesteron was found to be of no great significance in cortizol synthesis; 21-oxypregnenolone, but not progesteron proved to serve as the principal intermediate product in corticosterone formation.
