Description
Chitosan Oligosaccharide (COS) Refined grade is is a degradation product of chitosan/chitin via chemical hydrolysis or enzymatic degradation involving deacetylation and depolymerization processes.
Chitosan Oligosaccharide (COS) as class of natural polymers that has physiochemical properties including:low molecular weight (Mw), higher degree of deacetylation (DD), higher degree of polymerization (DP), less viscous and complete water solubility, which endowed it with significant biological properties like antimicrobial, antioxidant, anti-inflammatory and antihypertensive, as well as drug/DNA delivery ability.
