Rịba ama amaokwu a dị n'okpuru ma zaa ajụjụ ahụ mgbe e mesịrị n'otu asụsụ ahụ dị ka amaokwu ahụ:  Nkọwa: Ọdịdị nke chitin bụ Albert Hofmann kpebiri na 1929. Chitin bụ polysaccharide gbanwere agbanwe nke nwere nitrogen; a na-agwakọta ya site na nkeji nke N-acetyl-D-glucosamine (ka ọ bụrụ kpọmkwem, 2-(acetylamino)-2-deoxy-D-glucose). Mkpokọta ndị a na-eme njikọ β-(1→4) (dị ka njikọ dị n'etiti nkeji glucose na-etolite cellulose). Ya mere, enwere ike ịkọwa chitin dị ka cellulose nwere otu hydroxyl otu na monomer ọ bụla dochie otu acetyl amine. Nke a na-enye ohere maka mmụba nke njikọ hydrogen n'etiti ndị polymer dị n'akụkụ, na-enye matriks chitin-polymer ike dị elu.  Ajụjụ: Gịnị bụ aha polysaccharide a gbanwere agbanwe nke Hofmann chọpụtara na 1929?
