Chitosan

Chitosan is a polymer composed of N-acetyl glucosamine and glucosamine, which is derived from chitin – an abundant natural polysaccharide found in the shells of crustaceans and in the cell walls of fungi. It has a wide range of applications and has been used in biomedical and industrial areas for many years. Chitosan is used for its antibacterial, antifungal, antiviral and anti-inflammatory properties, and is being explored for use in tissue engineering and wound-healing applications. It is also used as a biopolymer for encapsulating drugs and making films and coatings. In addition, it is used to purify wastewater because of its ability to remove heavy metals, oil and grease. Furthermore, its high water-solubility makes it ideal for use in food industries as an antioxidant and a preservative. Chitosan is increasingly being explored for its potential role in the health and sustainability of the modern world.
