The chitosan bandage is derived from chitin, a biodegradable carbohydrate found in the exoskeletons of countless animals, particularly shellfish. Chitosan, the second-most-common substance in the planets biomass, after cellulose, is also a polysaccharide, not a protein. As such, it will not cause allergic reaction. Although chitosan has virtually the same chemical structure as cellulose, it is a polysaccharide with a positive charge. When paired with the negative charge of red blood cells outer membranes, opposites attract, Dr. Gregory said. As a result, a clot is formed independent of the bodys normal clotting procedure. [...] The bandage literally has the power to create its own clot, even among those with hemophilia. Chitosan has long been known for its clotting abilities, but it had never been made into a reliable product.
