(a) Molecular structures of a POPC/POPG lipid molecule. Different lipid groups are colored differently: choline/glycerol in black, phosphate group in red, ester group in green, and other carbon atoms in blue. (b) Electron density profiles of the lipid choline/glycerol, phosphate, and ester groups. Here, we set the -position of bilayer at zero (). (c) Number of H-bonds formed between each amino residue of hIAPP and the three different groups in lipid heads: choline (POPC)/glycerol (POPG), phosphate, and ester groups.
