Nonuniform Donnan Equilibrium within Bacteriophages Packed with Dna
The curvature stress of DNA packed inside a phage is balanced against its electrostatic self-interaction. The DNA density is supposed nonuniform and as a result the Donnan effect is also inhomogeneous. The coarse-grained DNA density is a nonlinear function of the DNA radius of curvature at a given position inside the bacteriophage. It turns out that a region (or regions) exists totally free fro...
متن کاملMembrane Potentials in the Donnan Equilibrium
(The diagram gives, however, no indication of the hydrostatic pressure due to the liquid in the manometer tube, which is a necessary condition for equilibrium. For further details of the experiments Loeb's original papers and book s may be consulted.) AH and BH represent hydrogen electrodes; AK and BK, calomel electrodes connected to the solutions by saturated KC1. Loeb measured the potential d...
متن کاملMembrane Potentials in the Donnan Equilibrium. Ii
Measurements were made of electromotive force in the Donnan equilibrium of systems containing dilute solutions of protein and acid. Removal of the membrane produced a decrease of no more than 2 to 4 mv. in electromotive force, while the membrane potentials, as estimated by the usual arbitrary assumption, were of the order of 12 to 34 mv. Ion ratios, as calculated from analyses for total chlorid...
متن کاملBinding Effects in Multivalent Gibbs-Donnan Equilibrium
The classical Gibbs-Donnan equilibrium describes excess osmotic pressure associated with confined colloidal charges embedded in an electrolyte solution. In this work, we extend this approach to describe the influence of multivalent ion binding on the equilibrium force acting on a charged rod translocating between two compartments, thereby mimicking ionic effects on force balance during in vitro...
متن کاملChemical structure of erythrocytes with emphasis on Donnan equilibrium.
Hemoglobin is a major constituent of erythrocytes. Because it is non-diffusable and confined within a cell membrane and because of its buffering powers, three major physiochemical equilibria are involved in any acid or base change in blood. Ionic, osmotic and Donnan balance must be main tained.16 During the acidosis phase of cell ular respiration and increasing Pco2, bi carbonate enters eryt...
