Figure 4. Bending modulus of the model phospholipid membrane used in the simulations. The plot shows the relationship between the wavelength of the each of the undulatory modes of the membrane, 1/q, and the amplitude of these undulations, u. The slope of the linear fit (red line) is s = 1.8 × 10−7 Å−2. The corresponding value of kc is kB T (s A)−1 = 1.2 × 10−19 J, where A is the area of the membrane (Materials and methods). This value is in good agreement with that determined experimentally, namely, ∼10−19 J (Marsh, 2006).
