✦ Synopsis

Tissues of the starfish Distolasterias nipon contain large amounts of lipids derived from ethanediol ethers. The neutral lipid fraction yielded, by combined column and thin-layer chromatography, an individual compound of the type 1-alk-l'-enyl-2-acyl ethanediol and a group of saturated 1-alkyl-2-acyl derivatives of ethanediol. IR spectroscopy, gas chromatography and mass spectrometry showed the neutral plasmalogen to be the octadeca-l', 9'-dienyl ether of stearoyl ethanediol, while the main components of the saturated fraction were the hexadecyl and octadecyl ethers of stearoyl ethanediol. The high level of ether lipids containing ethanediol (about 35 % of the triglycerides) in starfish tissues shows that some organisms are producing diol derivatives as major components of lipid biosynthesis.
