  "notes": "front faces -Y; cut block of the phospholipid bilayer after the fluid mosaic model on a lilac base board: red hydrophilic heads on both outer faces, yellow hydrophobic fatty acid tails inside (two per lipid, one with a cis kink). On all four cut faces the lipids stand in profile, the top is covered with head balls. Embedded are a light blue channel protein of six subunits around an open pore through the whole membrane, two mint glycoproteins with branched sugar chains of lavender and pink beads and one glycolipid. No letters or numbers. One solid mesh, no movable parts.",
