The Swelling and Osmotic Pressure of Gelatin in Salt Solutions
1. The swelling and the osmotic pressure of gelatin at pH 4.7 have been measured in the presence of a number of salts. 2. The effect of the salts on the swelling is closely paralleled by the effect on the osmotic pressure, and the bulk modulus of the gelatin particles calculated from these figures is constant up to an increase in volume of about 800 per cent. As soon as any of the salts increas...
متن کاملSalt Effect on Osmotic Pressure of Polyelectrolyte Solutions: Simulation Study
We present results of the hybrid Monte Carlo/molecular dynamics simulations of the osmotic pressure of salt solutions of polyelectrolytes. In our simulations, we used a coarse-grained representation of polyelectrolyte chains, counterions and salt ions. During simulation runs, we alternate Monte Carlo and molecular dynamics simulation steps. Monte Carlo steps were used to perform small ion excha...
متن کاملOsmotic Pressure Measurements of Phase-Separating Protein Solutions
Measurements of the osmotic pressure of aqueous solutions of Bovine y-crystallin and of chicken-egg-white lysozyme were made as a function of solute concentration at T=20+1 °C. The equation of state for solutions of each of these proteins, of the form fll=f(c,T), was thus traced along this isotherm for protein concentrations up to 225 mg/ml. Osmotic pressure measurements were performed using a ...
متن کاملOsmotic volumes of distribution; idiogenic changes in osmotic pressure associated with administration of hypertonic solutions.
A RECENT paper from this laboratory (I) showed that the osmotic volume of distribution of sodium numerically approximates total body water when either sodium chloride or sodium sulfate is loaded in anesthetized, nephrectomized dogs and cats. The question of why these two sodium distributions appear to be identical was deferred. In extending osmometric analysis to this and related matters, we ex...
متن کاملOn the Influence of Aggregates on the Membrane Potentials and the Osmotic Pressure of Protein Solutions
1. It is shown that when part of the gelatin in a solution of gelatin chloride is replaced by particles of powdered gelatin (without change of pH) the membrane potential of the solution is influenced comparatively little. 2. A measurement of the hydrogen ion concentration of the gelatin chloride solution and the outside aqueous solution with which the gelatin solution is in osmotic equilibrium,...
