A research team showed that mice injected with this material have a buildup of interleukin-4 cells, characteristic of an allergic reaction, and this material has also been used by medical teams as a biodegradable suture. A similar structure has random portions of deacetylation and is more soluble in water, while a sample of this material over 25 million years old was discovered, proving its longevity. It has a structure that is similar to cellulose, with a hydroxyl group replaced by an acetylamine, and its unique properties are largely derived from the hydrogen bonding due to this difference. Composed of monomers of N-acetylglucosamide, FTP, identify this polymer found in the cell walls of fungi and the exoskeleton
