Ingabe i-cellulose i-polymer yemvelo noma yokwenziwa?

I-Cellulosei-polymer yemvelo, ingxenye ebalulekile yezindonga zamaseli ezitshalweni. Ingenye yezinhlanganisela eziningi kakhulu ze-organic Emhlabeni futhi isebenza njengempahla yesakhiwo embusweni wezitshalo. Uma sicabanga nge-cellulose, sivame ukuyihlobanisa nokuba khona kwayo okhunini, ukotini, ephepheni nakwezinye izinto ezihlukahlukene ezitholakala ezitshalweni.

Isakhiwo se-cellulose siqukethe amaketanga amade ama-molecule e-glucose axhunywe ndawonye ngamabhondi e-beta-1,4-glycosidic. Lawa maketango ahlelwe ngendlela evumela ukuthi akhe izakhiwo eziqinile, ezinezintambo. Ukuhlelwa okuyingqayizivele kwala maketango kunikeza i-cellulose izici zayo eziphawulekayo zokukhanda, okuyenza ibe yingxenye eyinhloko ekuhlinzekeni ukusekelwa kwesakhiwo ezitshalweni.

Inqubo ye-cellulose synthesis ngaphakathi kwezitshalo ihlanganisa i-enzyme cellulose synthase, eyenza ama-molecule e-glucose abe ngamaketanga amade futhi awakhiphe odongeni lweseli. Le nqubo yenzeka ezinhlotsheni ezahlukahlukene zamaseli ezitshalo, okunomthelela emandleni nasekuqineni kwezicubu zezitshalo.

Ngenxa yobuningi bayo kanye nezakhiwo ezihlukile, i-cellulose ithole ukusetshenziswa okuningi ngaphandle kwendima yayo kubhayoloji yezitshalo. Izimboni zisebenzisa i-cellulose ekwenzeni iphepha, izindwangu (njengokotini), nezinhlobo ezithile zama-biofuels. Ukwengeza, okuphuma ku-cellulose okufana ne-cellulose acetate nama-cellulose ethers asetshenziswa emikhiqizweni eminingi, okuhlanganisa imithi, izithasiselo zokudla, nezingubo zokugqoka.

Ngenkathii-cellulosengokwayo iyi-polymer yemvelo, abantu benze izinqubo zokuyilungisa futhi bayisebenzise ngezindlela ezihlukahlukene. Isibonelo, imithi yokwelapha ngamakhemikhali ingashintsha izakhiwo zayo ukuze iyenze ifaneleke kakhulu ukusetshenziswa okuthile. Kodwa-ke, ngisho nangamafomu ashintshiwe, i-cellulose igcina imvelaphi yayo yemvelo eyisisekelo, iyenze ibe into eguquguqukayo nebalulekile kuzo zombili izimo zemvelo nezinjiniyela.
