Apparent modification of forces between lecithin bilayers

DM LeNeveu, RP Rand, D Gingell, and VA Parsegian

Small sugar solutes effect variation in the equilibrium separation of lecithin bilayers in aqueous solution. Since sugars have negligible influence on bilayer structure, they probably act by modifying interbilayer forces. The observed widening and narrowing of the bilayer separation is correlated with the predicted weakening and strengthening of the attractive van der Waals forces between lipid bilayers that occurs with increasing sugar concentrations.
