WebEven though the receptors recognizing mannans and beta-1,3-glucans have been extensively studied to date, the epitope of the polysaccharide ligand is often not well defined. In addition, receptors recognizing other cell wall major components such as chitin, alpha-1,3-glucan or galactose polymers remain to be identified. WebChitosan hydrogels. Chitosan, (1,4)-2-acetylamino-2-deoxy- β - D -glucan, is the only natural alkaline polysaccharide found in nature. It is the product of chitin deacetylation and its repeat unit involves N -acetyl- D -glucosamine and D -glucosamine connected by a β - (1–4) glycosidic bond ( Fig. 5 a) [43].
