Hyaluronic acid is harder to stretch than Curdlan and chitin when pulled in water—it takes more energy, so it’s tougher and resists stretching more.
Claim Language
Language Strength
definitive
Uses definitive language (causes, prevents, cures)
The claim uses definitive language with 'requires' and 'significantly higher than' to assert precise, non-probabilistic energy values and a clear comparative outcome, implying certainty in the measured difference.

Hyaluronic Acid Unveiled: Exploring the Nanomechanics and Water Retention Properties at the Single-Molecule Level.
Scientists pulled apart individual HA molecules in water and found it took more energy to stretch than other similar materials like Curdlan and chitin, meaning HA is tougher to stretch — just like the claim says.
