Özet
The quantitative and qualitative fatty acid compositions of phospholipid and neutral lipid were investigated and compared for specimens of the freshwater mussel Unio elongatulus. Samples were collected from 4 different localities in Turkey: Cagcag Brook in Nusaybin (Mardin), Fabrika Brook in Cinar (Diyarbakir), the Tigris River under and Sigma SFA levels. As is characteristic of freshwater mussels, Sigma omega 6/Sigma omega 3 ratios were found to be high in all lipid fractions. the Sadi Bridge (Diyarbakir), and Kirkcesme Spring in Sultankoy (Mardin). Phospholipids and neutral lipids of the mussels' whole tissues were fractionated by thin layer chromatography (TLC) and fatty acid analyses were done by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). Both in the phospholipid and neutral lipid fractions, C16:0 (17.20%-22.17%), C16:1 omega 7 (9.21%-15.31%), C18:1 omega 9 (12.21%-23.12%), C18:2 omega 6 (12.12%-16.10%), and C20:4 omega 6 (5.86%13.10%) acids were found to predominate. The percentage of C20:4w6 acid, a precursor of eicosanoids, was shown to be high in the phospholipid fractions. In the neutral lipids, total monounsaturated fatty acids (Sigma MUFA) levels were determined to be higher than total saturated fatty acids (Sigma SFA) and total polyunsaturated fatty acids (Sigma PUFA) levels. In the phospholipid total, however, Sigma PUFA levels were noted to be higher than Sigma MUFA and Sigma SFA levels. As is characteristic of freshwater mussels, Sigma omega 6/Sigma omega 3 ratios were found to be high in all lipid fractions.
