General description
4-palmitamido-TEMPO/N-tempoyl-palmitamide is a spin label, that is present in the polar head-group region of the membrane.
This amphiphilic compound binds strongly to membranes by virture of its long hydrocarbon chain, but the polarity of the amide linkage is expected to localize the nitroxide function in the aqueous phase adjacent to the membrane surface. The location of the nitroxide function allows one to investigate electrostatic potentials and lipid-protein interactions at the membrane surface.
Application
4-palmitamido-TEMPO/N-tempoyl palmitamide (N-TP) may be used:
- to enrich rod outer segment (ROS) membranes
- as a spin probe in vesicles/bilayer to prepare samples for electron spin resonance (ESR) experiments
- as a component in liposomes to assess the mobility of lipid headgroups

G-protein-coupled receptors are membrane proteins that are regulated by a small family of arrestin proteins. During formation of the arrestin-receptor complex, arrestin first interacts with the phosphorylated receptor C terminus in a pre-complex, which activates arrestin for tight receptor binding.

γ-AApeptides are a new class of antibacterial peptidomimetics that are not prone to antibiotic resistance and are highly resistant to protease degradation. It is not clear how γ-AApeptides interact with bacterial membranes and alter lipid assembly, but such information is
