Webthe ionic interaction (F) varies as the inverse of the dielectric constant (e), the ionic interac-tion would be stronger in the protein environment, with the smaller dielectric constant. 2. Biological Advantage of Weak InteractionsThe interactions between biomolecules are often sta-bilized by weak interactions such as hydrogen bonds. WebFeb 22, 2004 · Empirical studies have shown that, in real ecosystems, species–interaction strengths are generally skewed in their distribution towards weak interactions. Some theoretical work also suggests that weak interactions, especially in omnivorous links, are important for the local stability of a community at equilibrium.
