Chitosan, a remarkable natural polysaccharide, is gaining increasing attention for its diverse applications across multiple industries. Understanding its fundamental science—from its chemical structure to its manufacturing process—is key to appreciating its potential. NINGBO INNO PHARMCHEM CO.,LTD. is proud to provide high-quality chitosan powder, rooted in a deep understanding of its scientific underpinnings.

Chitosan is a linear polysaccharide composed of randomly distributed β-(1→4)-linked D-glucosamine (deacetylated unit) and N-acetyl-D-glucosamine (acetylated unit). It is derived from chitin, the structural polymer found in the exoskeletons of arthropods, such as crustaceans, and in the cell walls of fungi. The process of converting chitin to chitosan involves deacetylation, typically achieved through treatment with an alkaline substance like sodium hydroxide. This process removes acetyl groups, increasing the number of free amine groups and rendering the polysaccharide soluble in dilute acids.

The key properties of chitosan that drive its utility include its biodegradability, biocompatibility, and its positive charge in acidic to neutral solutions. The presence of free amine groups allows chitosan to interact with negatively charged surfaces and molecules, which is fundamental to its applications in drug delivery, wound healing, and water purification. Its film-forming capabilities and antimicrobial activity further enhance its versatility.

The degree of deacetylation and molecular weight are crucial parameters that influence chitosan's physical and chemical properties, such as solubility, viscosity, and biological activity. By carefully controlling these factors during manufacturing, producers can tailor chitosan for specific applications. For researchers and product developers seeking to buy chitosan, understanding these scientific nuances ensures the selection of the optimal grade for their intended use. NINGBO INNO PHARMCHEM CO.,LTD. is committed to delivering chitosan products that meet rigorous quality standards, backed by scientific expertise.
