If you change the way sugar units are linked together in two natural substances—curdlan and chitin—to look more like the sugar links in hyaluronic acid (which your skin and joints use), they become better at soaking up water and stretch out more in solution.
Claim Language
Language Strength
definitive
Uses definitive language (causes, prevents, cures)
The claim uses the verb 'results in', which implies a direct and certain outcome from the intervention, indicating a definitive causal relationship rather than a possibility or correlation.

Subject
The β-(1-3) or β-(1-4) glycosidic bonds in curdlan and chitin
Action
Replacing
Target
a mixed β-(1-3) + β-(1-4) linkage pattern, as found in hyaluronic acid, resulting in polysaccharides with enhanced water affinity and more extended molecular conformations

Hyaluronic Acid Unveiled: Exploring the Nanomechanics and Water Retention Properties at the Single-Molecule Level.
The study found that hyaluronic acid, which has a mix of two types of sugar links, holds more water and stretches out more than curdlan or chitin, which have only one type of link. This suggests that changing curdlan or chitin to have the same mix would make them better at absorbing water and stretching out.
