The frequently studied polysaccharide, chitosan oligosaccharide/chitooligosaccharide
(COS) is the major degradation product of chitosan/chitin via chemical hydrolysis or …

Chitosan is a natural polycationic linear polysaccharide derived from chitin. The low
solubility of chitosan in neutral and alkaline solution limits its application. Nevertheless …

Despite the advantages presented by synthetic polymers such as strength and durability, the
lack of biodegradability associated with the persistence in the environment for a long time …

Chitin is the most abundant natural polysaccharide and chitosan is its most important
derivative. Regardless of having various bioactivities, the water insolubilities of chitin and …

Chitosan oligosaccharide (COS) is an oligomer of β-(1➔ 4)-linked d-glucosamine. COS can
be prepared from the deacetylation and hydrolysis of chitin, which is commonly found in the …

Insects could be a potential replacement of protein-rich ingredients in poultry diets. Among
these insects, black soldier fly (BSF), Hermetia illucens, has a high content of protein and fat …

Chitin and its N-deacetylated derivative chitosan are two biological polymers that have
found numerous applications in recent years, but their further deployment suffers from …

Chitosan is an abundant organic polysaccharide, which can be relatively easily obtained by
chemical modification of animal or fungal source materials. Chitosan and its derivatives …

Viral infections, in addition to damaging host cells, can compromise the host immune
system, leading to frequent relapse or long-term persistence. Viruses have the capacity to …

Biodegradable chitin is the second-most abundant natural polysaccharide, widely existing in
the exoskeletons of crabs, shrimps, insects, and the cell walls of fungi. Chitosan and …
