1962Nature 9 June 979/1 This experimental structure..is..liquid in the plane of the bilayer. 1964Jrnl. Molec. Biol. VIII. 149 Both faces of the bilayer are presumed to be covered with a molecular layer of protein. 1974Sci. Amer. Mar. 27/2 The lipids in membranes..form a bilayer, two layers back to back, so that their hydrophilic heads constitute the top and bottom surfaces of the membrane and their hydrophobic tails are buried in the membrane interior. 1976Nature 19 Feb. 601/1 When immersed in an excess amount of water, bilayers of zwitterionic lecithin form a lamellar lattice. 1982T.
