Purification of DP 6 to 8 chitooligosaccharides by nanofiltration from the prepared chitooligosaccharides syrup [PDF]
Bioresources and Bioprocessing, 2014 Abstract Background Chitooligosaccharides (COS) with degrees of polymerization (DP) 6 to 8 are degraded from chitosan, which possess excellent bioactivities. However, technologies that could purify them from hydrolysis mixtures in the narrow DP range (984 to 1,306 Da) are absent.

Production of Chitooligosaccharides and Their Potential Applications in Medicine [PDF]
Marine Drugs, 2010 Chitooligosaccharides (CHOS) are homo- or heterooligomers of N-acetylglucosamine and D-glucosamine. CHOS can be produced using chitin or chitosan as a starting material, using enzymatic conversions, chemical methods or combinations thereof. Production of well-defined CHOS-mixtures, or even pure CHOS, is of great interest since these oligosaccharides ...

Chitooligosaccharides for wound healing biomaterials engineering [PDF]
Materials Science and Engineering: C, 2020 Chitooligosaccharides (CHOS) are oligomers of β-(1-4) linked N-acetylglucosamine and D-glucosamine that are produced from chitin or chitosan using different enzymatic or chemical methods. CHOS are water-soluble and non-cytotoxic with diverse bioactivities such as antibacterial, anti-inflammation, anti-obesity, anti-tumor and antioxidant.

Cytotoxicity and genotoxicity of chitooligosaccharides upon lymphocytes [PDF]
International Journal of Biological Macromolecules, 2011 Two COS mixtures and a low molecular weight chitosan (LMWC) were tested for potential cytotoxicity and genotoxicity upon human lymphocytes. Genotoxicity was evaluated in vitro by cytokinesis-blocked micronucleus and alkaline comet assays, while cytotoxicity was assessed by flow cytometry analysis.
