Quitosana: derivados hidrossolúveis, aplicações farmacêuticas e avanços Chitosan: hydrossoluble derivatives, pharmaceutical applications and recent advances

Química Nova, 2006
Chitin and chitosan are copolymers build from N-acetyl-D-glucosamine and D-glucosamine. The former is widely found in nature and yields the latter on deacetylation. The copolymers are being used for several purposes.

Can we make Chitosan by Enzymatic Deacetylation of Chitin?

Molecules, 2019
Chitin, an insoluble linear polymer of β-1,4-N-acetyl-d-glucosamine (GlcNAc; A), can be converted to chitosan, a soluble heteropolymer of GlcNAc and d-glucosamine (GlcN; D) residues, by partial deacetylation.
