Abstract

Chitin and chitosan should be considered as derivatives of cellulose. The basis for such an approach to these polysaccharides is their chemical structure. The macromolecular chains of these polymers are formed by glucopyranose cycles, which, being connected by β- (1→4) glucosidic bonds, form linear polymer chains. The biological functions and mechanical properties of these polysaccharides are largely determined by the conformation of macromolecules and the distribution of reactive groups in them. Due to the unique properties of chitin and chitosan, they are becoming increasingly important in the practical and especially in the medical and biological activities of mankind. The aim of this work is to obtain chitin from Apis Mellifera, obtaining chitosan from chitin, synthesis of the Schiff base chitosan with acetic, salicylic, o - methoxy - p -hydroxy benzaldehyde and dialdehyde gossypol, study of the composition and individuality of the obtained products using IR spectroscopy methods.
