Chemical preparation and structural characterization of a homogeneous series of chitin/chitosan oligomers.
TL;DR: The modeling of these distributions by means of a binomial law displayed that the chemical N-acetylation of low DP GlcN oligomers, produced in a homogeneous medium, occurs randomly along the oligosaccharide chains in accordance with a statistical (Bernoullian) arrangement.
Journal ArticleDOI
Chitosan and oligochitosan enhance the resistance of peach fruit to brown rot.
TL;DR: The findings suggest that the effects of chitosan and oligochitOSan on disease control and quality maintenance of peach fruit may be associated with their antioxidant property and the elicitation of defense responses in fruit.
Journal ArticleDOI
Anti-inflammatory Effects of Low-molecular Weight Chitosan Oligosaccharides in IgE-antigen Complex-stimulated RBL-2H3 Cells and Asthma Model Mice
TL;DR: The results suggest that the oral administration of LM-COS is effective in alleviating the allergic inflammation in vivo and thus can be a good source material for the development of a potent therapeutic agent against mast cell-mediated allergic inflammatory responses and airway inflammation in allergic inflammatory diseases, including asthma.
Journal ArticleDOI
Structure and function of enzymes acting on chitin and chitosan
TL;DR: Current knowledge on the structure and function of enzymes involved in the conversion of these polymeric substrates, including chitinases, chitosanases, glycoside hydrolase families 8, 46, 75 and 80 are reviewed.
Journal ArticleDOI
Nitric oxide-releasing chitosan oligosaccharides as antibacterial agents
TL;DR: The secondary amine-modified chitosan oligosaccharides greatly increased the NO payload over existing biodegradable macromolecular NO donors and enabled their penetration across the extracellular polysaccharides matrix of Pseudomonas aeruginosa biofilms and association with embedded bacteria.

Food applications of chitin and chitosans
TL;DR: Application of chitinous products in foods and pharmaceuticals as well as processing aids has received considerable attention in recent years as exotic synthetic compounds are losing their appeal.
Journal ArticleDOI
Antibacterial action of chitosan
TL;DR: Fungal chitosan had significantly less antibiotic effect than CH and CL, and was shown to be concentration dependent with 0.1 mg/mL more effective than 2.0 and 5.0 mg/ mL.
Journal ArticleDOI
Chitosan: A Unique Polysaccharide for Drug Delivery
TL;DR: The aim of this review is to give an insight into the many potential applications of chitosan as a pharmaceutical drug carrier.
BookDOI
Chitin in nature and technology
TL;DR: Chitin has been a landmark for polysaccharides and modified chitins, besides chitin itself, to the point that three International Conferences on Chitin / Chitosan were convened (Boston, U.S. A. 1977, Sapporo, Japan 1982 and Senigallia, Italy 1985).
Journal ArticleDOI
Antimicrobial effect of chitooligosaccharides produced by bioreactor
TL;DR: In this paper, the antibacterial effect of three kinds of chitooligosaccharides with relatively higher molecular weights (HMWCOS), medium molecular weight (MMWCOS), and lower molecular weight, respectively, was evaluated against various microorganisms.
