PROTASAN
Ultra Pure Chitosan

The Protasan product range is a series of ultra pure and well characterized water soluble chitosan chloride and glutamate salts with low levels of endotoxins and proteins. Chitosan is a linear polysaccharide composed of randomly distributed beta-(1→4)-linked D-glucosamine and N-acetyl- D-glucosamine. It is produced commercially by deacetylation of chitin, the structural element in the exoskeleton of crustaceans, with its viscosity primarily dependent on the average molecular weight of the polymer.

Chitosan is a biocompatible, biodegradable, bioadhesive, cationic, polyamine with a high charged density and readily binds to negatively charged surfaces such as mucosal membranes. It also enhances the transport of polar drugs across epithelial surfaces.
