Method One of the most easily accessible quantities to monitor in an NPT ensemble is the total area A of a bilayer with Nchol cholesterol molecules and NDPPC DPPC molecules in each monolayer. One can then define the area per total lipid a(x) as a function of the mole fraction of cholesterol, defined as x = Nchol/(NDPPC + Nchol)
Comments For large values of x. See BNID 105809, 105804, 105805, 102781, 105300
