title: Alteration of erythrocyte (see article) -ATPase by replacement of cholesterol by desmosterol in the membrane.
abstract: Cholesterol of red blood cells (RBC) is readily exchanged by desmosterol and vice versa. The resulting alteration in the sterol composition influences the specific (Na+ plus K+)-ATPase activity. It is suggested that this effect is due to an altered membrane fluidity.
