oxygen, leading to the formation of cis Δ5:6-cholestene-3 : 4-diol, suggested that this reactive primary oxidation product may play an important role in the metabolism of cholesterol and the sexual hormones. Experimental confirmation of this view was obtained by feeding experiments, which showed that the diol, as well as its intermediate dehydration product cholestenone, were converted into coprosterol
