Radix peregra (Müller, 1774) Tatlısu Salyangozunun Fosfolipit, Diaçilgliserol, Triaçilgliserol ve Total Lipidinin Yağ Asidi Dağılımı.

Abstract

Öz: Hazian 2009 tarihinde Sultanköy köyünden (Mardin) toplanan tatlısu salyangozu Radix peregra'ın(Gastropoda: Pulmonata) fosfolipit, diaçilgliserol, triaçilgliseıol ve totat lipit yağ asiti kompozisyonu kalitatif ve kantitatif olarak araştırıldı. Salyangozun tüm vücut lipitleri ince tabaka kromatografi ile fraksiyonlandı. Gaz kromatografi (GC) aleti kullanılarak salyangozun fosfolipit, diaçilgliserol, triaçilgliserol ve total lipit yağ asidi kompozisyonu analizlendi. Yüzde dağılımda en çok Cl6:0 (%20.98-%25.68), C18:1ω9 (%14.08-%18.41) ve Cl8:2 ω6 (%8.27-%l4.28). asitler tespit edildi. Eikosanoidlerin öncül maddesi olan C20:4ω6 (%9.05) ve C20:5ω3 (%8.48) asitlerin yüzde oranlan fosfolipit fraksiyonunda daha yüksek bulundu. Total ÇDYA oranı en fazla fosfolipit frakiyonunda; total TDYA ile total DYA oranı ise en fazla diaçilgliserol ve triaçilgliserol fraksiyonunda saptandı. Salyangozun diaçilgliserol ile triaçilgliserol fraksiyonlan kalitatif ve kantitatif olarak benzerlik gösterdi. Abstract: Quantitative and qualitative fatty acid composition of phospholipid, diacylglycerol, triacylglycerol and total lipid of freshwater snail Radix peregra (Gastropoda: Pulmonata), collected from Sultanköy village (Mardin) in June 2009, were invesligated. Whole body lipids of the snail were fractionaled by thin layer chromatography. The fatty acid compositions of phospholipid, diacylglycerol, triacylglycerol and total lipid of the snail were analyzed by using capillary gas chromatography (GC). In the percentages, C16:0 (20.98%-25.68%), Cl8:lω9 (14,08%-18.41%) and Cl8:2ω6 (8.27%-14.28%) acids were the most abundant components. The percentages of C20:4ω6 (9.05%) and C20:5ω3 (8.48%) acids, precursors of eicosanoids, were defined higher in lhe phospholipid fraction. The highest proportion of total PUFA was found in phospholipid; the highest proportion of total MUFA and total SFA were found in diacylglycerol and tiacylglycerol fractions. Quantitiative and qualitative content of diacylglycerol and triacylglycerol fractions of the snail were similar each other
