Influence of membrane binding of protofibrillar Aβ trimers on the order of the head and the tail atoms of POPG lipids in the upper leaflet of the bilayer. The order parameter SCD for the sn-1 chain (a) and sn-2 chain (b) of POPG as a function of carbon atom index. (c) Area per lipid as a function of simulation time. For each Aβ-POPG system, both the SCD values and the area per lipid are the average over the four different MD runs using the last 50 ns simulation data. The SCD and the area per lipid of a neat POPG lipid bilayer are also given for comparison.
