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

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 ...

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 ...

Chito-oligosaccharides derived from Tilapia Fish Scales; A Powerful Antioxidant

Research Journal of Pharmacy and Technology, 2023
Fish scales are a good source of chitin and collagen that can be used in various cosmetic, biomedical, pharmaceutical, and food industries due to their stability and environmental friendliness. The antioxidant activities of chito-oligosaccharides derived from fish scales evaluated via i) DPPH free radical scavenging activity, ii) superoxide anion ...

Preparing Chito-Oligosaccharides as Antimicrobial Agents for Cotton

Textile Research Journal, 1999
Cotton fabric with good antimicrobial activity and durability to washing is obtained by using chito-oligosaccharides without the need for a binding chemical as a crosslinker. The fully deacetylated chitosan is depolymerized into chito-oligosaccharide using sodium nitrite. The average degree of polymerization (DP) of chito-oligosaccharide is determined

A reliable reducing end assay for chito-oligosaccharides

Carbohydrate Polymers, 2004
The enzymatic degradation of chitin typically yields a mixture of chito-oligosaccharides of different size. This degradation process can be followed by measuring the production of reducing ends. We show that the widely used Schales' procedure does not permit accurate determination of reducing ends since the signal increases with the length of the chito-

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.

Preparation of antimicrobial sodium alginate with chito‐oligosaccharide side chains

Journal of Polymer Science Part A: Polymer Chemistry, 2001
AbstractTo provide sodium alginate (SA) with an antimicrobial property, we introduced chito‐oligosaccharide (COS) via chemical bonding in a two‐step procedure. We reacted COS with N‐methylol acrylamide (NMA) with N‐methylol groups to prepare acrylamidomethyl chito‐oligosaccharide (COS–NMA).
