N-furoyl chitosan (NF-CS) and N-furoyl chitosan oligosaccharide (NF-COS) were prepared via acylation of chitosan and chitosan oligosaccharide. Their chemical structures and physical properties were characterized by Fourier transform infrared spectroscopy, (1)H NMR, X-ray diffraction, and elemental analysis.

Chito-Oligosaccharides (COS) With Anti-Aging Effect From Flammulina velutipes
Carbohydrate Polymer Technologies and ApplicationsChito-oligosaccharides (COS) with a degree of deacetylation (DD) of 67.85 % and a degree of polymerization (DP) ranging from 2 to 6 was prepared from Flammulina velutipes (F. velutipes). The COS was confirmed as α-form by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and Nuclear magnetic resonance analysis (NMR).

We describe the synthesis of N-trifluoroacetyl chito-oligosaccharides and their use as ligands to probe the binding sites of wheat-germ agglutinin, a lectin specific for N-acetylglucosamine. The binding is monitored using intrinsic protein fluorescence, which is due to tryptophan side-chains.

[The inactivating effect of chito-oligosaccharides on TMV particles in vitro].
Bing du xue bao = Chinese journal of virology, 2008To confirm the inactivating effect of chito-oligosaccharides on Tobacco mosaic virus (TMV) par ticles in vitro, the difference of TMV pathogenicity was evaluated according to the decrease of local lesion numbers after inoculating with TMV mixed with chito-oligosaccharides (DP3-10) in Nicotiana glutinosa, and the virion structural change was studied by ...
