| Abstract: | Plasma membranes of rabbit intestinal smooth muscle cells manifest low surface activity on the boundary of the electrolyte-air phases. This activity undergoes essential changes if the electrolyte surface is covered with the lecithin monolayer. According to the experimental data, the interaction of plasma membranes with the lecithin monolayers is hydrophobic in nature and essentially depends on the density of molecular packing of phospholipids in the monolayer and on the status of the membrane preparation. A possible mechanism of the formation of the monolayer patterns from cell membranes is discussed. |
