NASA confirmed chitosan elicits the same effect in plants on earth. Aldotriose Glyceraldehyde Ketotriose Dihydroxyacetone. Chitin is poorly valorised due to difficulties to be processed related to a bad solubilisation. Accounts of Chemical Research. Chitosan is produced commercially by deacetylation of chitinwhich is the structural element in the exoskeleton of chitosabe such as crabs and shrimp and cell walls of fungi.
Chitin and chitosan [Chitine et chitosane]. Bioinspired materialsa manufacturing concept inspired by natural nacreshrimp carapace or insect cuticles   has led to development of bioprinting methods to manufacture large cbitosane consumer objects using chitosan.
