Chitooligosaccharide-2,5-anhydro-D-mannonic Acid

Molbank, 2014
Chitooligosaccharide with one 2,5-anhydro-D-mannofuranose unit at the reducing end (COSamf) was prepared by nitrous deamination of fully N-deacetylated chitosan. The oxidation of the amf-unit by chlorite sodium was achieved in high yield.

Antidiabetic Effect and Mechanism of Chitooligosaccharides

Biological and Pharmaceutical Bulletin, 2010
The aim of this study was to observe the antidiabetic effect and mechanism of chitooligosaccharides (COS). Type 2 diabetic rats were fed a high-energy diet together with an injection of streptozotocin (STZ). After 8 weeks of COS treatment, the changes in glycometabolism, insulin sensitivity, serum hepatic marker enzyme levels, liver glycogen content ...

Developing an Analytical Framework for the Molecular Weight Analysis of Fish-Derived Collagen Peptides in Beverages: A Multi-Method Comparative Study. [PDF]

Food Sci Nutr
An analytical framework was developed for molecular weight analysis of fish‐derived collagen peptides in beverages. Three GPC methods were compared, and matrix interference from excipients was excluded using a 20.5 min cutoff. Cubic polynomial fitting significantly improved inter‐method consistency.

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 ...
