Evidence for the existence of cholesteryl alk-1-enyl ethers in bovine and porcine cardiac muscle

Abstract

Evidence is presented for the existence of cholesteryl alk-1-enyl ethers in bovine and porcine cardiac muscle. Several different fatty chains are present in the cholesteryl ethers, the major species having 16 and 18 carbon atoms. The cholesteryl alk-1-enyl ether concentration was found to be 0.08 and 0.01 μmoles/100 mg of neutral lipid in bovine and porcine cardiac muscle, respectively.
