Chitosan is a natural biodegradable and biocompatible polysaccharide, containing glucosamine and acetylglucosamine units.
Chitin's molecular weight is more than one million Da., it is found in fungi, arthropods and marine invertebrates. Chitosan is obtained from chitin by a deacetylation process, its molecular weight is less than six hundred thousand Da., Chitosan and chitin are insoluble in water.
Chitosan derivatives obtained from chitosan, their molecular weight is from 3,000 to 100,000 Da, most chitosan derivatives are water-soluble, and have lower viscosity.
Chitosan has been widely used in health food, pharmaceutical, cosmetics, agriculture, biomedical applications, water treatment, textile, etc.
MarkNature Chitosan and its derivatives source form chitin made from snow crab shells, their commercial production has been achieved.
