The Modification of Water Structure by Divalent Cations as a Mechanism of Membrane Permeability Control,

Abstract

The report is concerned with the effects of dehydration and solute concentration on cells which result when water is frozen out of solution. The observation that in the sucrose-ammonium chloride medium that is an expansion of the red cell membrane so that the cell can be suspended in solutions as hypotonic as 120 mosm before any tension develops on the membrane. Evidence is summarized showing that membrane area (structure) and permeability can be altered by various solutes in order of their stabilizing or destabilizing capacity, presumably through an influence on hydrophobic bonds and exposed nonpolar groups, probably through the intermediate agency of water.
