Tha Chitin na polysaccharide atharraichte anns a bheil nitrogen; tha e air a synthesized bho aonadan de N-acetyl-D-glucosamine (gus a bhith mionaideach, 2-(acetylamino)-2-deoxy-D-glucose). Tha na h-aonadan sin a 'cruthachadh covalent β-(1→4) - ceanglaichean (mar na ceanglaichean eadar aonadan glucose a' cruthachadh cellulose). Mar sin, chitin faodar a mhìneachadh mar cellulose le aon bhuidheann hydroxyl air gach monomer air a chuir an àite le buidheann acetyl. Tha seo a 'leigeil le ceangal hydrogen nas motha eadar polymers coisrigte, a' toirt air matrix chitin-polymer neart nas motha. Ceist: Dè an t-ainm a th 'aig polysaccharide atharraichte a lorg Hofmann ann an 1929?
chitin
