Chitosan and chitosan oligosaccharides (COS) have been reported to possess various
biomedical properties, including antimicrobial activities, immuno-enhancing effects, and anti …

Chitosan oligosaccharides (COSs) are widely used biopolymers that have been studied in
relation to a variety of abnormal biological activities in the food and biomedical fields. Since …

Chitooligosaccharides (COS) are the degraded products of chitin or chitosan. COS is water-
soluble, non-cytotoxic to organisms, readily absorbed through the intestine, and eliminated …

Previous reports indicate that N-acetyl-d-glucosamine oligomers (chitin oligosaccharide;
NACOS) and d-glucosamine oligomers (chitosan oligosaccharide; COS) have various …

Chitooligosaccharides, also known as chitosan oligomers or chitooligomers, are made up of
chitosan with a degree of polymerization (DP) that is less than 20 and an average molecular …

Chitosan oligosaccharides (COS) are the degraded products of chitin or chitosan prepared
by chemical or enzymatic hydrolysis. As compared to chitosan, COS not only exhibit some …

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 …

Abstract Background Chitosan oligosaccharides (COSs) are the degraded products
prepared from the deacetylation and depolymerization of chitin or chitosan using physical …

Cancer has become a main public health issue globally. The conventional treatment
measures for cancer include surgery, radiotherapy and chemotherapy. Among the various …

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 …
