[The effect of cholesterol level in erythrocyte membranes on the sedimentation rate, electrophoretic motility, and the rate of potassium ferricyanide reduction].

It has been found that with an increase of the molar ratio cholesterol/phospholipids in human erythrocyte membranes in vitro their sedimentation rate in diluted suspensions increases and the reduction rate of potassium ferricyanide decreases, while the electrophoretic mobility of erythrocytes is not changed. The effect of cholesterols discussed in terms of the mechanism of transmembrane transfer of reduction equivalents and non-equilibrium in the double electric layer of erythrocytes surface.
