Hyaluronic acid doesn’t stick to itself as much as other similar substances, so it’s more likely to mix with water instead — like how some glue is sticky and others just soak up water.

A meta-analysis pooling results from multiple molecular dynamics simulations comparing intrachain interaction energies of hyaluronic acid, curdlan, and chitin under identical computational conditions (force field, temperature, solvent model), with water interaction propensity quantified via radial distribution functions and hydrogen bond occupancy.

Direct measurement of self-binding strength of individual hyaluronic acid, curdlan, and chitin chains using atomic force microscopy or optical tweezers in aqueous buffer, comparing unbinding forces and binding kinetics.

Quantification of intrachain folding (self-binding) vs. hydration dynamics using FRET-labeled polymers in solution.

Measurement of heat changes during polymer self-association vs. water interaction to infer thermodynamic favorability.

Theoretical comparison of intrachain binding energy landscapes using quantum mechanical or molecular mechanics methods.
