Thoir iomradh air an earrann gu h-ìosal agus an uairsin freagair a 'cheist às deidh sin anns an aon chànan ris an earrann:  Passage: Chaidh structar chitin a dhearbhadh le Albert Hofmann ann an 1929. 'S e polysaccharide atharraichte a th' ann an chitin a tha a' toirt a-steach nitrogen; tha e air a synthesized bho aonadan de N-acetyl-D-glucosamine (gus a bhith mionaideach, 2-(acetylamino)-2-deoxy-D-glucose). Bidh na h-aonadan sin a' cruthachadh ceanglaichean covalent β-(1→4) (mar na ceanglaichean eadar aonadan glùcois a' cruthachadh cellulose). Mar sin, faodar chitin a mhìneachadh mar cellulose le aon bhuidheann hydroxyl air gach monomer air a chur an àite le buidheann acetyl amine. Tha seo a 'toirt cothrom do cheangal hydrogen nas motha eadar polymers coisrigte, a' toirt neart nas motha don matrix chitin-polymer.  Ceist: Dè an t-ainm a th' air polysaccharide leasaichte a lorg Hofmann ann an 1929?
