Abstract: Biomolecular stability, assembly, as well as its functions rely on the interplay between hydrogen bonding and dispersion forces. Hydrogen bonds shows both structural specificity and directional stability, as seen in DNA base pairing, whereas dispersion forces reinforce stability through non-specific interactions like base stacking as well as protein folding. Despite its low strength, dispersion forces cumulatively enhance biomolecular resilience. Computational tools such as the Non-Covalent Interaction (NCI) index helps in visualizing these interactions by analyzing both reduced density gradient (RDG) and electron density (ρ). Understanding these forces is very essential for the advancement of biomolecular research, drug design, and biomaterials engineering.
