Computational Assessment of Chito-Oligosaccharides Interactions With Plasma Proteins [PDF]

open access: yesMarine Drugs, 2021
It is widely rec ognized that chitin and chitosan are potential sources of bioactive materials and that their oligosaccharides reveal various biological activities (including antimicrobial) that are correlated with their structures and physicochemical ...

PVA Containing Chito-Oligosaccharide Side Chain

Polymer, 2000
Abstract A chito-oligosaccharide (COS) with the number average degree of polymerization (DP n ) of 9 was immobilized on poly(vinyl alcohol) (PVA) by crosslinking with a bifunctional compound, N -methylolacrylamide (NMA). The reaction was composed of two successive steps, the reaction of COS with NMA in an acidic medium in the first step and the ...

Chemical Modification of Silk Fibroin With N-Acetyl-Chito-Oligosaccharides

International Journal of Biological Macromolecules, 1996
N-Acetyl-chito-oligosaccharides (NACOS)-silk fibroin (SF) conjugates (NACOS-CY-SF) were prepared by the reaction of solubilized SF and cyanuric chloride (CY)-activated NACOS modifier (NACOS-CY). N-Acetyl-D-glucosamine (NAG), as a model compound, was reacted with CY to clarify the chemical structure of the modifier.

Conformational properties of chito-oligosaccharides: titration, optical rotation, and carbon-13 N.M.R. studies of chito-oligosaccharides

Carbohydrate Research, 1981
Abstract Several chito-oligosaccharides [β-(1→4)-linked oligosaccharides of 2-amino-2-deoxy- d -glucose] have been studied. A semi-empirical treatment of titration and rotation data indicates that the glycosidic torsion-angles (ΔΦ and ΔΨ) are all closely similar throughout the oligomers and also in the polymer (chitosan), in their fully protonated ...

Antibacterial activity of Chito-oligosaccharides derived from Fish Scales

Research Journal of Pharmacy and Technology, 2022
This study aimed to evaluate the antibacterial activity of chito-oligosaccharides (COS) from Tilapia fish scales. There is a massive potential in sustainably prospecting from these resources: algae, vertebrate, crustaceans, molluscs, residues from fish farms, and fisheries such as bones, skin, and fins, internal organs and non-bio-degradable substances
