Abstract:

A hypothesis of biological differentiation of sodium and potassium through lipid phase transitions in the bimolecular leaflets of biological membranes has been probed using lecithin micelles, which may be considered ordered, the temperature coefficient of the solubilizing power of lecithin for a sodium dye salt is negative and that for the potassium salt of the same dye, is positive. These results indicate that order-disorder transitions within biological systems may provide the physical basis for changes in ionic mobility in biological membranes. Author
