Ingabe i-cellulose iyi-polymer yemvelo noma yokwenziwa?

I-Celluloseiyi-polymer yemvelo, ingxenye ebalulekile yezindonga zamaseli ezitshalweni. Ingenye yamakhemikhali e-organic amaningi kakhulu eMhlabeni futhi isebenza njengezinto zokwakha embusweni wezitshalo. Uma sicabanga nge-cellulose, sivame ukuyihlanganisa nokuba khona kwayo okhunini, ekotini, ephepheni, nakwezinye izinto ezahlukahlukene ezithathwe ezitshalweni.

Isakhiwo se-cellulose sakhiwe ngamaketanga amade ama-molecule e-glucose axhunywe ndawonye ngezibopho ze-beta-1,4-glycosidic. La maketanga ahlelwe ngendlela ewavumela ukuthi akhe izakhiwo eziqinile, ezine-fibrous. Ukuhleleka okuyingqayizivele kwala maketanga kunikeza i-cellulose izakhiwo zayo ezimangalisayo zemishini, okwenza kube yingxenye ebalulekile ekuhlinzekeni ukwesekwa kwesakhiwo ezitshalweni.

Inqubo yokwenziwa kwe-cellulose ezitshalweni ihilela i-enzyme i-cellulose synthase, epholisha ama-molecule e-glucose abe amaketanga amade bese iwakhipha odongeni lweseli. Le nqubo yenzeka ezinhlotsheni ezahlukene zamaseli ezitshalo, okufaka isandla ekuqineni nasekuqineni kwezicubu zezitshalo.

Ngenxa yobuningi bayo kanye nezakhiwo zayo eziyingqayizivele, i-cellulose ithole ukusetshenziswa okuningi ngale kwendima yayo ku-biology yezitshalo. Izimboni zisebenzisa i-cellulose ekukhiqizeni iphepha, izindwangu (njengokotini), kanye nezinhlobo ezithile zamafutha e-biofuel. Ngaphezu kwalokho, izinto ezitholakala ku-cellulose ezifana ne-cellulose acetate kanye ne-cellulose ethers zisetshenziswa emikhiqizweni eyahlukahlukene, kufaka phakathi imithi, izithasiselo zokudla, kanye nokugqoka.

Ngesikhathii-cellulosengokwayo iyi-polymer yemvelo, abantu baye basungula izinqubo zokuyiguqula nokuyisebenzisa ngezindlela ezahlukene. Isibonelo, ukwelashwa ngamakhemikhali kungashintsha izakhiwo zayo ukuze ifaneleke kakhulu ekusetshenzisweni okuthile. Kodwa-ke, ngisho nasezinhlotsheni eziguquliwe, i-cellulose igcina imvelaphi yayo yemvelo eyisisekelo, okwenza ibe yinto eguquguqukayo futhi eyigugu kokubili ezimweni zemvelo nezobunjiniyela.
