Significance of electron interactions of fatty acids of phospholipid molecules in the organism adaptation to habitat temperature

Data in the fatty acid composition of muscle tissue phospholipids of some representatives of gastropod molluscs (Gastropoda) have been presented for the first time. In the lake phytophagues Lymnaea stagnalis and Lymnaea ovata the long-chained C22-acid was not detected, where-as in the predator commo...

Description
Summary:Data in the fatty acid composition of muscle tissue phospholipids of some representatives of gastropod molluscs (Gastropoda) have been presented for the first time. In the lake phytophagues Lymnaea stagnalis and Lymnaea ovata the long-chained C22-acid was not detected, where-as in the predator common whelk Buccinum undatum, C22:6ω3 was present. Comparison of absorption spectra (240-720 nm) of lipid extracts of the studied invertebrates and of rat has been performed. The obtained data are discussed from the point of view of participation of π-electrons of phospholipid fatty acid molecules in adaptation of membranes to the habitat temperatures, which arises owing to interelectron attraction and to the process of formation of Cooper's pairs.
