Variations in the fatty acid compositions of the liver and gonad tissue of spiny eel (Mastacembelus mastacembelus) from Atatürk Dam Lake. Turkish Journal of Biochemistry, 42(6), 617-623.0250-4685https://www.degruyter.com/document/doi/10.1515/tjb-2017-0045/htmlhttps://hdl.handle.net/11468/13714Objective: The aim of the study was to investigate quantitative and qualitative fatty acid profiles of the gonad and liver tissue of female Mastacembelus mastacembelus (spiny eel). Methods: Total lipids were extracted with 5 mL of chloroform-methanol (2:1 v/v). Samples containing gonad and liver lipid were transesterified with acidified methanol. The fatty acid methyl esters were extracted with hexane. Fatty acids were detected by gas chromatography (GC). Results: The major saturated fatty acids (SFAs) were myristic acid (C14:0), palmitic acid (C16:0) and stearic acid (C18:0) in both gonad and liver tissue. Oleic acid (C18:1 ω-9) and palmitoleic acid (C16:1 ω-7) were the prominent monounsaturated fatty acid (MUFA). The dominant polyunsaturated fatty acids (PUFAs) were linoleic acid (LA, C18:2 ω-6), arachidonic acid (AA, C20:4 ω-6), docosapentaenoic acid (C22:5 ω-3) and docoesahexaenoic acid (DHA, C22:6 ω-3). The ratio of ω-3/ω-6 ranged from 1.55 to 3.44 and 1.18 to 2.71 in the gonad and liver tissue, respectively. Conclusion: The findings of this study will be useful for understanding the seasonal distribution of fatty acid composition in the liver and gonad of spiny eel.eninfo:eu-repo/semantics/openAccessFatty acidFreshwater fishGonadLiverMastacembelus mastacembelusVariations in the fatty acid compositions of the liver and gonad tissue of spiny eel (Mastacembelus mastacembelus) from Atatürk Dam LakeVariations in the fatty acid compositions of the liver and gonad tissue of spiny eel (Mastacembelus mastacembelus) from Atatürk Dam LakeArticle426617623WOS:0004239895000052-s2.0-8503759241710.1515/tjb-2017-0045Q3Q4
