WebJan 1, 2011 · Because of the preferential interaction of cholesterol with sphingolipids, it should be enriched in the non-cytosolic leaflet of the membrane. However, experimental evidence instead suggests a very high ratio between cholesterol and phospholipids in the cytosolic leaflet (Mondal et al., 2009). This finding is presently difficult to interpret in ... WebSep 30, 2015 · In effect, when a pH gradient is not present, the charged lipids cannot spontaneously cross the plasma membrane due to the strong membrane dielectric capacity. On the contrary, lipids in the inner leaflet and in contact with the low internal pH of the liposome can absorb a proton therefore becoming a lipid of neutral charge.
