TWO deep-sea gastropods, Ifremeria nautilei and Alr~iniconcha hessleri, collected on a hydrothern~al site of the North Fiji Basin (Southwestern Pacific) were analysed for polar and neutral lipids using gas-liquid chromatography/mass spectrometry. A high level of monounsaturated fatty acids (MUFAs) and a low level of 0 3 series polyunsaturated fatty aclds (PUFAs) indicated that nutrition of both gastropods was related to a food web based malnly on bacterial supply. From differences In MUFA distribution between the 2 gastropods, it appeared that most of the energy requirements of A hessleri were supplied by sulfur-oxidizing endobacteria whereas 1. nautllei probably had a mixotroph~c diet based on endogenous as well as exogenous bacteria. Given the relat~vcly high level of linoleic acid, which represented from 2 to 8"b of the phospholipid fatty acids, hydrothermal gastropods did not appear to be depleted in m6 PUFAs. It was hypothesized that they obtain linoleic acid from a pathway different to that in heterotrophic marine molluscs. In contrast to 0 6 PUFAs, both hydrothermal gastropods appeared to b e depleted in 0 3 PUFAs, indicating the limited importance of photosynthesisbased food supplies. Some non-methylene-interrupted dienes, particularly 20:209,15 which represented from 9 to 18% of the phospholipid fatty acids, may be synthesized by deep-sea symbiotic molluscs in order to restore the depleted w3 PUFAs considered a s essential for animals. Gills of both gastropods had high levels of neutral lipids, mainly MUFAs that may have originated from degradation of endobacterial phospholipids.

“…Lipid composition and storage strategy in molluscs, particularly of bivalves and gastropods have been studied since lipids constitute a major fraction of molluscan tissues (Voogt, 1983). Almost concern the entire organism and only a few reports on the tissue distribution of fatty acids are available (Hagar and Dietz, 1986;Wenne and Polak, 1989) Nutritional state can vary both seasonally and annually .Freshwater and marine water bivalve's display marked seasonal variations in weight and biochemical content of the soft tissue.…”

The total lipid, fatty acid content of some organs and whole specimen of freshwater mussel Unio elongatulus were investigated. The mussels were collected in July in 2007 from Tigris River, Turkey. Fatty acid content of selected tissues and whole mussel was analyzed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). In the analyses, predominant fatty acids were C16:0, C16:1ω7, C18:1ω9, C20:1ω9, C20:4ω6 and C20:5ω3. Analyses of selected organs (mantle, gills, foot and whole body) presented different and characteristic fatty acids profiles. In the gills C16:1ω7 (30.2%), C16:0 (17.4%) acids; in the mantle C18:1ω9 (20.3%), C16:0 (25.4%) acids; in the foot C16:0 (20.8%), C16:1ω7 (15.9%), C18:1ω9 (15.4%) acids and in whole body C16:1ω7 (27.6%), C16:0 (23.6%) acids were the most abundant constituents. Also the percentages of C20:4ω6 and C20:5ω3 acids, precursors of eicosanoids, were apparently high in the gills and foot. It is presumed that the chief fatty acids present in a particular organ are related to specific functions of the organ. In all of the tissue analyses, ΣMUFA levels were higher than ΣPUFA and ΣSFA levels. Midyenin bütün vücut dokusu ile seçilmiş organlarının yağ asidi içeriği gaz kromatografi (GC) ve gaz kromatografi-kütle spektrometre (GC-MS) ile analiz edildi. Analizlerde, C16:0, C16:1ω7, C18:1ω9, C20:1ω9, C20:4ω6 ve C20:5ω3 asitler yoğunlukta bulunan bileşenlerdi. Analiz edilen organlar (manto, solungaç, ayak ve tüm vücut) farklı ve karakteristik yağ asidi profili gösterdi. Solungaçta C16:1ω7 (%30,2), C16:0 (%17,4) asitler; mantoda C18:1ω9 (%20,3), C16:0 (%25,4) asitler; ayakta C16:0 (%20,8), C16:1ω7 (%15,9), C18:1ω9 (%15,4) asitler ve tüm vücut dokusunda ise C16:1ω7 (%27,6), C16:0 (%23,6) asitler en çok bulunan bileşenlerdi. Ayrıca eikosanoidlerin öncül maddesi olan C20:4ω6 ve C20:5ω3 asitlerin yüzde oranları, solungaç ve ayakta önemli oranda yüksek bulundu. Belirli organlardaki temel yağ asitlerinin organların spesifik fonksiyonları ile bağlantılı olduğu sanılmaktadır. Tüm doku analizlerinde, ΣTDYA oranı, ΣDYA ve ΣÇDYA oranlarından daha yüksekti.Anahtar Kelimeler: Yağ asitleri, tatlısu midyesi, Unio elongatulus, Dicle Nehri.
