TLDR
Chitin is the most abundant natural amino polysaccharide and is estimated to be produced annually almost as much as cellulose, and recent progress in chitin chemistry is quite noteworthy as mentioned in this paper.Abstract:
Chitin is the most abundant natural amino polysaccharide and is estimated to be produced annually almost as much as cellulose. It has become of great interest not only as an underutilized resource, but also as a new functional material of high potential in various fields, and recent progress in chitin chemistry is quite noteworthy. The purpose of this review is to take a closer look at chitin and chitosan applications. Based on current research and existing products, some new and futuristic approaches in this fascinating area are thoroughly discussed.read more

Chitin and chitosan polymers: Chemistry, solubility and fiber formation
TL;DR: In this paper, a review discusses the various attempts reported on solving this problem from the point of view of the chemistry and the structure of these polymers highlighting the drawbacks and advantages of each method and proposes that based on considerations of structure-property relations, it is possible to obtain chitin fibers with improved strength by making use of their nanostructures and/or mesophase properties of chitins.

Utilization of prawn waste: isolation of chitin and its conversion to chitosan
TL;DR: In this paper, the authors described a process for the preparation of chitosan from prawn waste, which involves extraction of protein using 0.5% sodium hydroxide solution, bleaching the protein free mass with bleach liquor containing 0.3-0.5 % available chlorine followed by demineralisation with 1.25 N hydrochloric acid in the cold and deacetylation using 1:1 (w/w) SH solution at 100°C for 2 hours.

Ph-dependent hydrolysis and drug-release of chitosan/polyether interpenetrating polymer network hydrogel
TL;DR: In this article, a novel hydrogel based on crosslinked chitosan with glutaraldehyde interpenetrating polyether polymer network was described, which can hydrolyse in acid at 37°C due to the cleavage of imine bonds within the network.
