Cover picture: A side view of the well-equilibrated dimyristoylphosphatidylcholine-cholesterol (DMPC-Chol) bilayer membrane at 4300 ps of molecular dynamics simulation. (a) The full system. (b) Water is removed to show locations of DMPC and Chol polar groups. The Chol molecules are shown as yellow sticks. The OH group of Chol is shown in standard colors as the CPK model; the nonester phosphate oxygen atoms (Op) are light blue; the carbonyl atoms O22 and O32 are light brown and pink, respectively. The spheres representing the oxygen atoms are of varying sizes; Ops are the smallest, O32s are the largest. The remaining atoms are coded in standard colors as lines.
