Excerpt
In view of the prominant role which proteins play in all biological phenomena it may be considered appropriate that a survey of the problem of the structure and properties of the proteins be included in a symposium on permeability. Proteins are one of the most essential constituents of cell membranes and the problem of the mechanism of the permeability of cells to water and solute molecules is intimately related to the problem of the structure of the proteins themselves. Unfortunately very little is known about the chemical and physical properties of those proteins which are present in the cell membranes. Also it is not known whether these proteins possess the same properties on the surface of the membranes which they would possess if they were dispersed in the liquid phase, or whether the transition from the liquid phase to the cell surface may have caused significant changes in the structure...
