Spontaneous Phase

Using coarse grain molecular dynamics simulations, the spontaneous phase separation in the ternary (POPC [1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine]/cholesterol/GM1) and quaternary (POPC/PSM[palmitoyl sphingomyelin]/cholesterol/GM1) lipid bilayers into liquid ordered (Lo) and liquid disordered (Ld) domains, due to self-aggregation of GM1 molecules and co-localization of cholesterol with GM1 in accordance with experiments, is studied.
