Chitosan charge
WebChitosan definition: A polysaccharide derived from chitin, that absorbs heavy metals while in solution: it is used in industry, esp. to purify waste water. WebThe high charge density of chitosan at pH levels below the pK a results in polyelectrolyte formation, whereas a low charge density at neutral pH contributes to its low cytotoxicity and facilitates the intracellular release of biomolecules. It is reported that the low charge density leads to low solubility, and aggregation.
