Rat and human adrenal gland preparations were incubated with radioactive cholesterol and 23,24-dinor-5-cholen-3 beta-ol, the latter being a proposed intermediate in the sesterterpene pathway for steroid biosynthesis. Steroids were isolated, purified by TLC and crystallised to constant specific activity. It was found that rat and human adrenal glands can utilise 23,24-dinor-5-cholen-3 beta-ol to produce androstenedione and dehydroepiandrosterone. Also, it was found that the conversion of 23,24-dinor-5-cholen-3 beta-ol to androgens occurs in the microsomal fraction. It was concluded that the sesterterpene pathway for steroid biosynthesis can function in the rat and human adrenal glands to produce androgens and that the intermediates are converted to androgens in the microsomal fraction.
