Synthesis of Hetero-chitooligosaccharides
Chitooligosaccharides are composed of linear β-(1→4)-linked 2-acetamido-2-deoxy-β-D-glucopyranose (GlcNAc) and/or 2-amino-2-deoxy-β-D-glucopyranose (GlcN). They are of interest due to their remarkable biological properties including antibacterial, antitumor, antifungal and elicitor activities. They …

Mass spectrometric analysis of chitooligosaccharides and their interaction with proteins
Chitooligosaccharides are composed of glycosamin and N-acetylglycisamin residues. Gel permeations chromatography is employed for the separation of oligomers, cation exchange chromatography is used for the separation of homologes and isomers. Trideuterioacetylation of the chitooligosaccharides …

Solution and solid phase synthesis of N,N'-diacetyl chitotetraoses
… of GlcN and GlcNAc) occurs in certain fungi. Chitooligosaccharides of mixed acetylation patterns are of interest for the determination of the substrate specificities and mechanism of chitinases. In this report, we describe the chemical synthesis of three chitotetraoses namely …

Darstellung von Chitinderivaten zur antimikrobiellen Ausrüstung von Textilien
… was depolymerized with sodium nitrite to produce chitooligosaccharides. The degree of polymerization was determined by colorimetry. Furthermore, chitosan was modified with quaternary ammonium groups to get a better soluble product and at the same time a better effect against bacteria. For this, …

Production and characterization of the recombinant wheat chitinase Wch1 and generation of chitin-specific antibodies
… assay allowing simple and rapid detection of chitooligosaccharides released from the degradation of chitin substrate in a fermenter. This assay would constitute a valuable tool for monitoring as well as quality assessment of the oligomers throughout the of the production process. The strategy …

Synthese und Glycosidasehemmung von Thio-analogen Kohlenhydraten
Chitin ist ein Polysaccharid, welches aus N-Acetylglucosamin (GlcNAc) aufgebaut ist. Das Biopolymer kommt in der Natur in Invertebraten, Algen, Pilzen und Einzellern vor. Chitinasen hydrolysieren Chitin. Diese Enzyme sind essentiell für die Regulierung und Entwicklung von Arthropoden und …
