Abstract

AbstractA number of free sterols and sterol esters of three freshwater mussels was separated and identified. A slow rate of biosynthesisde novo of sterols was demonstrated inAnodonta cygnea. Injected cholesterol was found to undergo esterification, oxidation, Δ22‐dehydrogenation and C‐24 alkylation. Methyl‐[14C]methionine was proved to be incorporated in C‐24 alkylsterols. Abnormally large amounts of cholesterol injected inA. cygnea were metabolized toward restoration of the normal composition of sterols. This was achieved by intensified metabolism of cholesterol, mainly by conjugation, oxidation and Δ22‐dehydrogenation.
