The total lipid (TL) and fatty acid (FA) contents in tissues and body segments were studied in adult Antarctic krill (Euphausia superba) caught in three regions of the Atlantic sector of Antarctica with different environmental conditions. Significant differences in lipid and FA status of the Antarctic krill tissues and body segments were observed in the regions. Main metabolic indices indicating quality of lipids showed that E. superba has a high nutritional value. In particular, lipids are highly unsaturated in the species and ratios of physiologically significant and essential FAs are favorable to human health. This was assumed to be a distinctive biochemical characteristic of the species. Data from the study can be used to form a scientifically based approach to further technological processing of raw krill and targeted extraction of certain substances and components of a lipid nature.
对在南极大西洋海域三个环境条件不同的区域捕获的成年南极磷虾（Euphausia superba）的组织和身体部分中的总脂质（TL）和脂肪酸（FA）含量进行了研究。在这些区域中，观察到南极磷虾组织和身体部分的脂质和FA状态存在显著差异。表明脂质质量的主要代谢指标显示，南极磷虾具有很高的营养价值。特别是，该物种的脂质高度不饱和，生理上重要的和必需的FA的比例有利于人类健康。这被认为是该物种独特的生化特征。该研究的数据可用于形成一种基于科学的方法，以进一步对磷虾原料进行技术加工，并针对性地提取某些具有脂质性质的物质和成分。
