The effects of water-soluble solutes on the phase transitions of phospholipids.
A previous treatment [Sturtevant, J.M. (1982) Proc. Natl. Acad. Sci. USA 79, 3963-3967], based on ideal solution theory, of the influence of small molecules on the main phase transitions of phospholipid bilayers is extended to include the effect of water solubility of the added solute. This effect is manifested primarily in a sharpening of the phase transition, resulting from a buffering by the aqueous phase of the concentration of the solute in the lipid phases.
