Adaptation to supercooling did not affect distinctly the fatty acid composition of brain total lipids but altered the fatty acid composition of phospholipids: amount of unsaturated acids was increased mainly due to an increase in concentrations of oleic, arachidonic and docosapentaenic acids. The same alterations occurred in brain phospholipids of the animals after a single cooling. The content of unsaturated fatty acids (mono-, dienic and polyenic acids) was distinctly decreased in spinal cord lipids during adaptation to supercooling. In the phospholipid fraction content of polyenic acid was only slightly decreased, while the content of moo- and dienic acids was considerably diminished. Decrease in content of polyenic acids was the most distinct in the animals, subjected to single supercooling immediately before decapitation.
适应过冷状态并未明显影响脑总脂质的脂肪酸组成，但改变了磷脂的脂肪酸组成：不饱和酸的含量增加，主要是由于油酸、花生四烯酸和二十二碳五烯酸浓度的增加。单次冷却后动物脑磷脂也出现了同样的变化。在适应过冷状态期间，脊髓脂质中不饱和脂肪酸（单烯、二烯和多烯酸）的含量明显降低。在磷脂部分，多烯酸的含量仅略有下降，而单烯和二烯酸的含量则大幅减少。在断头前立即进行单次过冷处理的动物中，多烯酸含量的下降最为明显。
