Abstract

Lipid and phospholipid compositions of an endemic deep-water freshwater gammarid, belonging to the subphylum Crustacea, Acanthogammarus grewingkii was studied. Content of alkenylacyl, alkylacyl and diacyl forms in the main phospholipid classes (phosphatidylethanolamine and phosphatydilcholine) were established using reaction micro-thin-layer chromatography. The fatty acids compositions of total lipids, neutral, glyco- and phospholipid fractions were investigated by capillary gas chromatography-mass spectrometry. Seventy-nine fatty acids were identified: 26 saturated (iso-, anteiso- and cyclo-), 26 monoenoic, 7 dienoic, 14 trienoic and 16 tetra-, penta- and hexaenoic. A number of demospongic fatty acids, such as 5,9–25:2, 5,9,19–26:3, 5,9,17–26:3, 5,9,23–28:3 and 5,9,21–28:3 acids, were found.

贝加尔湖特有淡水动物群的比较研究。深海片脚甲壳类棘鱼(Acanthogammarus)磷脂和脂肪酸组成

研究了一种特有的深海淡水甲壳亚门棘鱼的脂质和磷脂组成。用反应微薄层色谱法测定了主要磷脂类(磷脂酰乙醇胺和磷脂酰胆碱)中烯酰酰基、烷基酰酰基和二酰基的含量。采用毛细管气相色谱-质谱联用技术研究了总脂、中性脂、糖和磷脂组分的脂肪酸组成。鉴定出79种脂肪酸:26种饱和脂肪酸(异、前、环)，26种单、7种二、14种三、16种四、五、六烯脂肪酸。发现了5,9 - 25:2、5,9,19 - 26:3、5,9,17 - 26:3、5,9,23 - 28:3和5,9,21 - 28:3等多种脱海绵脂肪酸。
