[Fatty acid composition of aminophospholipids of the protein microenvironment in synaptosome plasma membranes in the rat brain].
Fatty acid composition of the aminophospholipids present in protein microenvironment of the plasmatic synaptic membranes was studied by covalent binding method. The analysis of fatty acids was carried out by gas liquid chromatography. Aminophospholipid fatty acids in the protein microenvironment were found to be more unsaturated compared to the lipids of the free bilayer. The fatty acids of the aminophospholipids present in the protein microenvironment of the plasmatic synaptic membranes were compared to those of rhodopsin microenvironment in photoreceptor membrane. The obtained results are discussed from the point of view of the signal transmission in the excitable membranes.
