Antimicrobial Activity of Hetero-Chitosans and Their Oligosaccharides with Different Molecular Weights
TL;DR: It was apparent that the growth of Gram-negative bacteria is less inhibited in the presence of the heterochitosans and their oligosaccharides than Gram-positive bacteria.
Journal ArticleDOI
Bioactive chitin derivatives. Activation of mouse-peritoneal macrophages by O-(carboxymethyl)chitins
TL;DR: Although there was remarkable enhancement of accessibility to lysozyme upon modification at O-6 of the GlcNAc residue, the accessibility was decreased by further substitution atO-3.
Journal ArticleDOI
Effect of dietary chitosans with different viscosity on plasma lipids and lipid peroxidation in rats fed on a diet enriched with cholesterol.
TL;DR: The observed influence of chitosan with different viscosity on the plasma lipid level, liver lipids and lipid peroxidation suggests that, while the hypocholesterolemic action of ch itosans with different Viscosity was similar, changes in the liver lipid status depended on their molecular weight when the deacetylation degree was comparable.

Angiotensin I Converting Enzyme (ACE) Inhibitory Activity of Hetero-Chitooligosaccharides Prepared from Partially Different Deacetylated Chitosans
TL;DR: Angiotensin I converting enzyme (ACE) inhibitory activity of hetero-chitooligosaccharides (hetero-COSs) prepared from partially different deacetylated chitosans was investigated by Lineweaver-Burk plots, and the inhibition pattern was found to be competitive.

Copper sorption by chitosan in the presence of citrate ions: influence of metal speciation on sorption mechanism and uptake capacities.
TL;DR: The present work investigates the sorption of copper by chitosan in the presence of citrate at different metal/ligand ratios and finds that copper sorption capacity strongly increases up to pH 4.5-5.5.
