The rates of transfer of [14C]cholesterol from small and large unilamellar cholesterol/egg yolk phosphatidylcholine vesicles to a common vesicle acceptor were compared at 37°C. The rate of exchange of cholesterol between vesicles of identical cholesterol concentrations (20 mol%) did not differ from the rate of transfer from donor vesicles containing 20 mol% cholesterol to egg yolk PC vesicles. Further, the rate of transfer of [14C]cholesterol from vesicles containing 15 mol% dicetyl phosphate (to confer a negative charge) was not different from the rate of transfer from neutral vesicles. However, the half-time for transfe of [14C]cholesterol from large unilamellar donor vesicles was about 5-times greater (10.2 h, 80 nm diameter) than from small unilamellar vesicles (2.3 h, 23 nm diameter). These data suggest that increased curvature in small unilamellar vesicles reduces cholesterol-nearest neighbor interactions to allow a more rapid transfer of cholesterol into the aqueous phase.
