GlossaryElectrostatic Interactions

forces between charged particles, either attracting or repelling

Electrostatic interactions, also known as Coulombic interactions, are forces between charged particles. These forces can be attractive or repulsive depending on the nature of the charges involved: opposite charges attract, while like charges repel. In biological systems, electrostatic interactions play a crucial role in the structure and function of molecules, such as the binding of proteins to DNA or the stability of cell membranes.
