Abstract
- Discusses how the configurations that adapt membrane proteins to lipids allow them to contact with two environments can be observed with electron-microscope techniques. Reference to the membrane proteins which are interescalated among the lipid molecules and dispersed over the membrane in patches; Constraints imposed by the specific environment of the lipid bilayer; Research on the water-soluble proteins that consist of regular conformations of the polypeptide chain; Features of the alpha helix which composes the backbone of the chain; Diffraction patterns yielded by X rays and the electrons which interact with the atomic nuclei; Isolation of the information associated with repetitive details from the random fluctuations liked to noise.
