Ion Channels: Structure and Function. Ion channels are membrane protein complexes and their function is to facilitate the diffusion of ions across biological membranes. Membranes, or phospholipid bilayers, build a hydrophobic, low dielectric barrier to hydrophilic and charged molecules. They are electrical insulators.
The inert gas xenon (chemical symbol Xe) has an atomic number of 54, and it has 54 protons in its nucleus. The number of neutrons varies, however.
Uses of Xenon. Xenon is used in photographic flashes, in high pressure arc lamps for motion picture projection, and in high pressure arc lamps to produce ultraviolet light. It is used in instruments for radiation detection, e.g., neutron and X-ray counters and bubble chambers.ses of Xenon.
