Ion and molecule
WebIon-dipole forces describe the electrostatic attraction between an ion and a neutral molecule with a dipole. The ion will attract one side of the dipole and repel the other. Dipoles in polar molecules are caused by a difference in electronegativities greater than 0.4. The formula for the ion-dipole potential is: \( E = \frac{ -k q_1 \mu } {r ... Web12 apr. 2024 · Early endoplasmic reticulum calcium ion release, increased ceramide level, proteasomal inhibition, and upregulation of microRNA-190b were suggested to be essential in modulating tocotrienol-mediated ERS/UPR transduction. Nevertheless, the upstream molecular mechanism of tocotrienol-induced ERS is largely unknown.
