description

For the first time it has been proven that cholest-4-ene-3-one is an endogenous constituent of adrenal tissue. Concentrations of cholestenone in quartered rat adrenals after 3 hours of in vitro incubation were comparable to those of progesterone. However, from specific radioactivities of tissue cholesterol and progesterone and from those of tissue cholestenone and progesterone after incubations with either 4-14C-cholesterol or 4-14C-cholestenone it has been concluded that, at best, cholestenone plays a minimal role as a C27-intermediate of corticosteroid biosynthesis.
