Information @ a Glance

 

  • 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 a positively charged lipophilic fiber derived from shellfish. It binds to negatively charged fats during digestion and reduces their absorption.
  • Chitosan is a substance that has recently found many applications in industry, agriculture and medical sciences. This natural polymer is characterised by optical chirality, and the specific rotation [α]Tλ, degree of deacetylation (DD) and mean molecular weight Mv are the most important parameters describing it.
  • Chitosan is, at the pH of the gastrointestinal tract, a positively charged polymer and can bind to negatively charged substances. It is believed that chitosan, similar to cholestryamine, has bile acid sequestration activity and that this may be the mechanism for its hypocholesterolemic effect.
  • Chitosan exhibits exceptional adsorption characteristics especially for heavy metals, which are causing a serious concern in wastewater streams. Immobilization of chitosan onto low-cost substrate significantly improves its feasibility in water treatment plants.
  • Chitosan as well as other polysaccharides irradiated with electron beam or gamma rays undergo degradation. As a result the molecular weight of these polymers is decreased, and molecular weight distribution is changed towards the most probable.
  • Chitosan activates resistance against pathogens after exposure: Production of chitosans from shrimp shells for applications in plant disease protection.
  • Chitosan is an extraordinary fat binder. Chemically speaking, Chitosan is an amino polysaccharide that has the ability to “bind” lipids in the stomach before they are absorbed through the digestive system into the bloodstream.  
  • Chitosan is a copolymer of N-acetyl glucosamine and glucosamine units and is represented as a homopolymer. It is a unique basic polysaccharide with high molecular weight. Chitosan occurs in nature in the cell walls of some fungi, insects etc. 
  • A chitosan-containing complex was more effective at stabilising citrus flavours and could offer a cost-effective alternative to gum arabic, suggests joint Italian-US research.
  • Chitosan is a cationic carbohydrate polymer derived from chitin. It has gained rapid and widespread acceptance as a diet aid. Chitosan also has many other industrial, pharmaceutical, agricultural, and cosmetic applications. A combination of these uses can result in very large daily intakes of chitosan by consumers.
