“…Arrachydic-C20H4002, arachidonic-C20 H32 02 (5,8,11,14 eicosatetraenoic), elaidic-C,8 H36 02 (9-bC), lauric -C,2H2402 and stearic C,8 H34 02 acids were investigated as cells containing thin films of smectic C (SmC) liquid crystals (LC), sandwiched between transparent electrodes of 5n02. These FA and Ch -C2-, H45 OH can be found in the biological membrane, as components or forerunner.…”
