| Abstract | The existence of ether-linked phospholipids, including 1-O-alk-l'-enyl-2-acyl and 1-O-alkyl-2-acyl-sn-glycero-3phosphocholines and ethanolamines, in bonito Euthynnus pelam/s (Linnaeus) white muscle, was investigated by gas chromatography and gas chromatography-mass spectrometry. Chemical ionization (/so-butane) mass spectrometry of trimethylsilyl ethers derived from the corresponding ether-linked glycerophospholipids proved effective not only for determining molecular weights but also for structural identification based on the ions [M -R] § [M -RO] + and [M + 1] +. 1-O-Alk-l"-enyl-2.acyl-snglycero-~phosphocholine and ethanolamine accounted for 3.0-6.0% and 3.6-7.6% of the total glycerophospholipids, respectively. 1-O-Alkyl-2-acylosn-glycero-3-phosphocholine and ethanolamine were also determined for one fish and accounted for 1.4% and 0.6% of the total glycerophospholipids, respectively. The predominant long chains in the sn-1 position of the glycerol moieties were 16:0, 18:0 and 18:1 in the case of the alkenylacyl and alkylacyl components. Fatty acid distribution of individual glycerophospholipids was also determined. Lipids 24, 363-370 (1989). |
