Chitosan Amphiphilic Derivatives. Chemistry and Applications
Chitosan is a natural polymer composed of randomly distributed -(1-4)-linked D-glucosamine (deacetylated unit) and Nacetyl-D-glucosamine (acetylated unit). It has been described as a non-toxic, biodegradable and biocompatible polymer with very interesting biological properties, such as permeation-enhancing and mucoadhesive properties, anticoagulant and antimicrobial activity and so on. Chitosan...

متن کاملNovel Amino-Pyridine Functionalized Chitosan Quaternary Ammonium Derivatives: Design, Synthesis, and Antioxidant Activity.
Chemical modification of chitosan is increasingly studied for its potential of providing new applications of chitosan. Here, a group of novel chitosan quaternary ammonium derivatives containing pyridine or amino-pyridine were designed and successfully synthesized through chemical modification of chitosan. Pyridine and amino-pyridine were used as functional groups to improve the antifungal activ...

متن کاملInfrared spectroscopy and thermal analysis of chitosan and its derivatives
Chitosan was prepared from crab shell. Different derivatives of chitosan e.g. phosphate, cyanoethyl and carboxymethyl chitosan are prepared. Molecular structure of chitosan and its derivatives was fallowed by infrared spectroscopy. A new band at 1715cm -1 (carboxyl group), at 2253cm -1 (cyano group) and at 1200cm -1 for (c-o-p) in spectra of carboxymethyl chitosan, cyanoethyl chitosan and chito...
