Abstract: | We consider three models of cholesterol distribution in the plane of a bilayer of DMPC. We analyse recent 2H-NMR data obtained from deuterated fluorescent probes and show that, on the characteristic time-scale of 2H-NMR, it is in accord with a random distribution of cholesterol in a fluid-like DMPC bilayer in a single phase at least for T greater than or approximately equal to 35 degrees C and for 0 less than or equal to c less than or equal to 0.42. |
