Metabolism in porifera VI. Role of the 5,6 double bond and the fate of the C-4 of cholesterol during the conversion into 3 β-hydroxymethyl-A-nor-5 α-steranes in the sponge Axinella verrucosa

During the conversion of cholesterol into 3 β-hydroxymethyl-A-nor-5 α-cholestane by the sponge Axinella verrucosa, the carbon-3 of this latter originate from carbon-4 of cholesterol. Cholestanol moreover does not seem an intermediate in this conversion.
