Abstract

Four Gastropoda species and two Bivalvia species from the Volga river basin were examined. 2. Distribution of phospholipids in the molluscs was studied by qualitative and quantitative micro thin-layer chromatography. 3. Major phospholipid classes, phosphatidylethanolamine and phosphatidylcholine, were found to contain plasmalogens. 4. One mollusc species notably contained 67 fatty acids including 25 saturated (both iso and anteiso), 24 monoenoic, five dienoic, four trienoic and eight polyenoic compounds identified by capillary gas chromatography; fatty acid contents in the other studied species were considerably lower. 5. Relatively high concentrations of nonmethylene-interrupted fatty acids were detected in certain examined species.

摘要

对伏尔加河流域的4种腹足纲动物和2种双壳纲动物进行了检查。2. 采用定性和定量微薄层色谱法研究了软体动物中磷脂的分布。3. 发现主要的磷脂类，磷脂酰乙醇胺和磷脂酰胆碱含有缩醛磷脂。4. 通过毛细管气相色谱法鉴定出一种软体动物物种显著含有67种脂肪酸，包括25种饱和脂肪酸（异饱和脂肪酸和顺式异构饱和脂肪酸）、24种单烯酸、5种二烯酸、4种三烯酸和8种多烯酸化合物；其他研究物种中的脂肪酸含量则低得多。5. 在某些被检查物种中检测到相对较高浓度的非亚甲基中断脂肪酸。
