General description
Chitosan is a linear amino polysaccharide composed of approximately 20% β1,4-linked N-acetyl-D-glucosamine (GlcNAc) and approximately 80% β1,4-linked D-glucosamine (GlcN) that is prepared by the partial deacetylation of chitin in hot alkali.
Application
Chitosan is a biocompatible, antibacterial, and biodegradable polyelectrolyte with a variety of industrial and biomedical applications. Its chemical properties and low toxicity make it particularly suitable as a component of drug and gene delivery systems, and for the development of biodegradable films and scaffolds for tissue engineering.

Greetings I wish to know if this chitosan is soluble or insoluble in water. I also realized that there is water-soluble chitosan. Please kindly clarify the difference. I need them to do laboratory experiments.
1 answer-
This product has not been tested for it's solubility in water. However, one gram chitosan can be dissolved in a mixture of 100mL 10% acetic acid and 50mL methanol, and then precipitated from a precipitant consisted of 10mL ethanol and 90mL acetate ester. The treated chitosan should become soluble in acid-free water completely at 8.02mg/mL
