Ingabe i-polymer yemvelo noma yokwenziwa?

CelluloseIngabe i-polymer yemvelo, ingxenye ebalulekile yezindonga zeseli ezitshalweni. Ngenye yezinto eziningi eziphilayo eziphilayo emhlabeni futhi zisebenza njengezinto ezihlelekile embusweni wezitshalo. Lapho sicabanga nge-cellulose, sivame ukusihlonza ngobukhona bayo ngokhuni, ukotini, ephepheni, nezinye izinto ezahlukahlukene ezisuselwa kwezitshalo.

Ukwakheka kwe-cellulose kuqukethe amaketanga amade e-glucose molecule exhumeke ndawonye nge-beta-1,4-glycosidic bond. Lawa maketanga ahlelwe ngendlela ebavumela ukuba bakhe izinhlaka eziqinile, ezinobuhlakani. Ukuhlelwa okuhlukile kwalawa maketanga kunikeza i-cellulose izakhiwo zayo zemishini emangazayo, okwenza kube yingxenye ebalulekile ekuhlinzekeni ukwesekwa okuhlelekile ezitshalweni.

Inqubo ye-cellulose synthesis ezitshalweni ifaka phakathi ukuhlanganiswa kwe-enzyme cellulose, okuyinto polymerizes glucose molecule emaketangeni amade futhi ayikhiphe odongeni lweseli. Le nqubo yenzeka ezinhlotsheni ezahlukahlukene zamaseli ezitshalo, okufaka isandla emandleni nasekuhluzeni kwezicubu zezitshalo.

Ngenxa yenala yaso nezakhiwo ezihlukile, i-cellulose ithole izicelo eziningi ezingaphezu kweqhaza lazo kwi-biology yesitshalo. Izimboni zisebenzisa i-cellulose ekhiqizweni lephepha, izindwangu (ezinjengokotini), nezinhlobo ezithile ze-biofuel. Ngokwengeziwe, ama-cellulose derivativeveves afana ne-cellulose acetate kanye neziphathamandla ze-cellulose asetshenziswa emikhiqizweni eminingi ehlukahlukene, kufaka phakathi amakhambi, izithasiselo zokudla kanye nezimbobo.

Laphocellulosengokwayo i-polymer yemvelo, abantu basungule izinqubo zokuguqula nokusebenzisa ngezindlela ezahlukahlukene. Isibonelo, izindlela zokwelapha amakhemikhali zingaguqula izakhiwo zayo ukuze zikwenze zilungele izinhlelo ezithile. Kodwa-ke, ngisho nasezindaweni eziguquliwe, i-cellulose igcina umsuka wayo oyisisekelo wemvelo, okwenza kube yinto eguquguqukayo futhi ebalulekile kuzo zombili izimo zemvelo nezobunjiniyela.
