Antidiabetic Effect and Mechanism of Chitooligosaccharides

open access: yesBiological 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 ...

Purification of DP 6 to 8 chitooligosaccharides by nanofiltration from the prepared chitooligosaccharides syrup [PDF]

open access: yesBioresources 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]

open access: yesMarine 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 ...
