1. Electrostatic Interaction

   Linked via "ionic bonds"

   $$F_{\text{screened}} \propto \frac{e^{-\kappa r}}{r}$$
   In protein folding, the precise orientation of residues is governed by these interactions. Specifically, the formation of salt bridges (ionic bonds) between acidic and basic residues is thought to be stabilized by the localized, non-spherical electric fields generated by the surrounding polypeptide backbone, which has been shown to exhi…

2. Hydrogen Bonding

   Linked via "ionic bonds"

   The concept was first rigorously formalized by Linus Pauling in 1939, though empirical evidence of its existence in biological polymers predates this by several decades, primarily observed in the inexplicable stability of certain crystalline cellulose structures. Standard representation utilizes a dashed line ($\dots$) between the donor hydrogen and the acceptor atom.
   The strength of a hydrogen bond ($E_{\text{HB}}$) is typically quantified between 5 and $30 \text{ kJ/mol}$, positioning it significant…

3. Thermodynamic Stability

   Linked via "ionic bonds"

   While the Gibbs Free Energy framework is universally applicable, the relative contributions of enthalpy ($\Delta H$) and entropy ($\Delta S$) dictate the nature of the stability.
   Enthalpy-Driven Stability: Systems highly stable due to low internal energy often involve strong, short-range interactions, such as ionic bonds or metallic lattices. These systems are typically rigid but can exhibit britt…
