  • Chitosan is a linear polysaccharide composed of randomly distributed ß-(1-4)-linked D-glucosamine (deacetylated unit) and N-acetyl-D-glucosamine (acetylated unit). It has a number of commercial and possible biomedical uses. Chitosan is produced commercially by deacetylation of chitin , which is the structural element in the exoskeleton of crustaceans (crabs, shrimp, etc.). The degree of deacetylation (%DA) can be determined by NMR spectroscopy, and the %DA in commercial chitosans is in the range 60-100 %.
  • Chitosan is extracted from the shells of crustaceans, such as shrimp and crab.It is formed through a process of deacylation of the Chitin molecule. Chitin/Chitosan is also a constituent part of cell walls of parasitic fungi.Chitosan is bioadhesive and readily binds to negatively charged surfaces such as mucosal membranes. Chitosan enhances the transport of polar drugs across epithelial surfaces, and is biocompatible and biodegradable. Purified qualities of chitosans are available for biomedical applications.
  • Chitosan and its derivatives such as trimethylchitosan (where the amino group has been trimethylated) have been used in non-viral gene delivery. Trimethylchitosan, or quaternised chitosan, has been shown to transfect breast cancer cells; with increased degree of trimethylation increasing the cytotoxicity and at approximately 50% trimethylation the derivative is the most efficient at gene delivery.
  • Chitosan is used primarily as a plant growth enhancer, and as a substance that boosts the ability of plants to defend against fungal infections. It is approved for use outdoors and indoors on many plants grown commercially and by consumers. The active ingredient is found in the shells of crustaceans, such as lobsters, crabs, and shrimp, and in certain other organisms.
  • Chitosan can also be used in water processing engineering as a part of a filtration process. It is also useful in other filtration situations, where one may need to remove suspended particles from a liquid. Chitosan, in combination with bentonite, gelatin, silica gel, isinglass, or other fining agents is used to clarify wine, mead, and beer.
  • Chitosan's properties allow it to rapidly clot blood, and has recently gained approval in the USA for use in bandages. The bandages include a layer of carefully produced chitosan that, when applied to a wound, causes rapid clotting, stopping the bleeding. Chitosan is hypoallergenic, and has natural anti-bacterial properties, further supporting its use in field bandages.
  • Like dietary fiber, chitosan is not digestible but may have beneficial effects on the gastrointestinal tract. Chitosan appears to reduce the absorption of bile acids or cholesterol; either of these effects may cause a lowering of blood cholesterol.A small human study found that taking 3-6 grams per day of chitosan for two weeks reduced indicators of putrefaction in the intestines,8 a change that might help prevent diseases such as colon cancer.
  • Chitosan is a positively charged lipophilic fiber derived from shellfish. It binds to negatively charged fats during digestion and reduces their absorption. Chitosan is available generically from numerous manufacturers.
