negatively stimulated glycosaminoglycan, and is one of the most important components of the extracellular matrix [72,73]. Hyaluronic acid can combine with the CD44 glycoprotein receptor, which is frequently over-expressive in a variety of carcinogenic cells, using the receptor connecting interrelation. ...
The solubility of the chitosan depends on the medium being used to dissolve it; in acid mixtures with water, it is soluble, but it is insoluble in common organic solvents [51,52]. The reason for its solubility can be explained due to the presence of amino groups that transforms chitosan ...
Solubility of chitosan One gram of chitosan was dissolved in 99 ml of distilled water with 1% glacial acetic acid using a magnetic stirrer for 30 min. The sample was extracted, the residue was filtered out using Whatman No. 1 filter paper, and then the sample was weighed, according to Kuma...

The introduction of the phthaloyl group into the chitosan matrix increases its solubility in organic solvent, film formability, flexibility, low methanol permeability, and with suitable ion conductivity. Maximum proton conductivity with composite membranes is attained at an intermediate loading of N-...

In general, polysaccharide blends have several advantages compared to blends with protein(s) and/or lipid(s), as the films are of low material cost, the resources for the films are abundant, they are relatively stable, and have better heat sealability and water solubility (K. Li, Zhu, ...
