Three types of lipids are present in membrane systems depending on the headgroup: cardiolipin (CL), phosphatidylglycerol (PG), phosphatidylethanolamine (PE). PE-and CL-lipids are charged lipids. Each CL-and PE-lipids contribute -2 and -1 respectively. Required number of monovalent Na ions are added for charge balance of the system. PE-lipids are present in highest proportion in all the membrane systems (about 73%), PG-lipids exist in intermediate quantity (22%), and, cardiolipins are present in least amount (only 5%). Based on saturation level in acyl chains, total five types of lipids are there: cyclopropane ring containing lipids (cyp.), fully saturated lipids (sat.), monounsaturated lipids (monounsat.), diunsaturated lipids (diunsat.), and triunsaturated lipids (triunsat.). NM system holds cyp., monounsat., and diunsat. lipids; MMS system contains sat., monounsat., and diunsat. lipids; MMU system comprises monounsat., diunsat., and triunsat. lipids. Lipid names, numbers, abundance, and presence of CP/unsaturations are listed in Table . The structure of the lipids both in all-atom (AA) and coarse grained (CG) resolution are shown in Table .
