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
