Synthetic Membrane (IMAGE) Max-Planck-Gesellschaft Caption Diagram of a synthetic membrane containing an odorant receptor molecule, shown here as a long chain. A spherical odorant molecule has bound to the odorant receptor. The left section of the membrane is comprised of lipid molecules, the right of block copolymer. In future, this polymer could replace the lipids, making the membrane stable in air.
