Halitta cellulose wani hadadden polymer ne wanda shine ainihin tsarin tsarin ganuwar tantanin halitta.Wannan polysaccharide yana taka muhimmiyar rawa wajen samar da ƙarfi, tsauri da goyan baya ga ƙwayoyin shuka, yana ba da gudummawa ga tsarin gaba ɗaya na ƙwayar shuka.
Cellulose na halitta shine polysaccharide, carbohydrate wanda ya ƙunshi dogayen sarƙoƙi na raka'o'in glucose wanda aka haɗa tare da haɗin β-1,4-glycosidic.Yana daya daga cikin mahadi masu yawa a duniya kuma ana samunsa da farko a cikin ganuwar tantanin halitta.Tsari na musamman na ƙwayoyin cellulose yana ba da naman shuka ƙarfi na ban mamaki da dorewa, yana mai da shi muhimmin sashi na tsarin shuka da aiki.
Tsarin cellulose na halitta
Asalin tsarin tsarin cellulose shine layin layi na kwayoyin β-D-glucose, wanda kowane rukunin glucose yana haɗuwa da naúrar glucose na gaba ta hanyar haɗin β-1,4-glycosidic.β-bonds suna ba wa cellulose tsarinsa na musamman na layi da maras reshe.Sabanin sitaci (wani polysaccharide da aka yi da glucose), yawancin kwayoyin halitta ba za su iya narkar da cellulose ba saboda kasancewar beta-linkages, wanda enzymes irin su amylase ba zai iya karya ba.
Maimaita raka'o'in glucose a cikin sarƙoƙi na cellulose suna samar da sarƙoƙi madaidaiciya madaidaiciya waɗanda aka haɗa tare ta haɗin haɗin hydrogen intermolecular.Wadannan shaidu suna ba da gudummawa ga samuwar microfibrils, wanda ke kara tarawa don samar da manyan sifofi da ake kira fibers cellulose.Tsarin waɗannan zaruruwa yana ba da ƙarfi da ƙarfi don shuka ganuwar tantanin halitta.
Tushen fiber na halitta
shuka:
Itace: Itace tana da arziki a cikin cellulose kuma shine babban tushen aikace-aikacen masana'antu.
Auduga: Fiber ɗin auduga kusan kusan celulose mai tsafta, yana mai da auduga ɗaya daga cikin mafi kyawun tushen halitta na wannan polymer.
Hemp: Kama da auduga, hemp fiber na farko ya ƙunshi cellulose.
Algae:
Wasu nau'ikan algae sun ƙunshi cellulose a cikin bangon tantanin su, wanda ke ba da gudummawa ga daidaiton tsarin waɗannan kwayoyin halitta na photoynthetic.
kwayoyin cuta:
Wasu kwayoyin cuta suna samar da cellulose, suna kafa wani Layer na kariya da ake kira biofilm.Wannan cellulose na kwayan cuta yana da kaddarorin musamman waɗanda ke sanya shi mahimmanci a aikace-aikace iri-iri.
Biosynthesis na cellulose
Cellulose biosynthesis yana faruwa da farko a cikin membrane plasma na ƙwayoyin shuka.Tsarin ya ƙunshi hadadden enzyme cellulose synthase, wanda ke haifar da polymerization na raka'a glucose cikin sarƙoƙi na cellulose.Ana fitar da waɗannan sarƙoƙi daga membrane na plasma kuma suna samar da microfibrils a bangon tantanin halitta.
Properties na halitta cellulose
Rashin narkewa:
Saboda tsarinsa na crystalline sosai, cellulose gabaɗaya baya narkewa a cikin ruwa da yawancin kaushi na halitta.
Hydrophilicity:
Ko da yake ba a iya narkewa, cellulose yana da kaddarorin hydrophilic, yana ba shi damar sha da riƙe ruwa.
Halin Halitta:
Cellulose abu ne mai lalacewa kuma saboda haka yana da alaƙa da muhalli.Ƙananan ƙwayoyin cuta irin su ƙwayoyin cuta da fungi suna da enzymes waɗanda ke rushe cellulose zuwa mahadi masu sauƙi.
Ƙarfin injina:
Tsari na musamman na ƙwayoyin cellulose yana ba da fibers cellulose kyakkyawan ƙarfin injiniya, yana sa su dace da aikace-aikace iri-iri.
Aikace-aikace na halitta cellulose
yadi:
Auduga galibi ya ƙunshi cellulose kuma shine babban ɗanyen kayan masaku.
Takarda da almara:
Itacen itace yana da wadata a cikin cellulose kuma ana amfani dashi wajen samar da takarda da kwali.
Aikace-aikacen likitanci:
Bacterial cellulose yana samun aikace-aikace a cikin suturar rauni, injiniyan nama, da isar da magunguna saboda haɓakar ƙwayoyin cuta da kaddarorinsa na musamman.
masana'antar abinci:
Abubuwan da aka samo asali na Cellulose, irin su carboxymethylcellulose (CMC), ana amfani da su a masana'antar abinci azaman masu kauri da stabilizers.
Biofuels:
Ana iya amfani da kwayar halitta ta cellulosic a matsayin abincin ciyarwa don samar da albarkatun halittu, yana ba da gudummawa ga makamashi mai dorewa.
Kalubale da makomar gaba
Duk da bambance-bambancen sa, akwai ƙalubale wajen haɓaka amfani da cellulose.Ingantattun hanyoyin hakowa, ingantattun halittu masu rai da haɓaka aikin kayan tushen cellulose sune wuraren bincike mai gudana.Bugu da ƙari, ci gaban fasahar kere-kere na iya ba da damar aikin injiniyan tsirrai tare da gyare-gyaren tsarin cellulose don takamaiman aikace-aikacen masana'antu.
Halitta cellulose shine polymer mai ma'ana tare da ganuwar tantanin halitta kuma yana taka muhimmiyar rawa wajen tsara kaddarorin jikin tsirrai.Tsarinsa na musamman yana haifar da tsari na raka'o'in glucose da ke da alaƙa da haɗin gwiwar β-1,4-glycosidic, yana ba da kyallen takarda mai mahimmanci da ƙarfi.Cellulose yana fitowa daga tushe iri-iri, daga itace zuwa auduga zuwa cellulose na kwayan cuta, yana ba shi aikace-aikace iri-iri a sassa daban-daban na masana'antu.
Yayin da fasaha da fasahar kere-kere ke ci gaba da ci gaba, binciken yuwuwar cellulose yana ƙaruwa.Daga amfanin al'ada a cikin masaku da takarda zuwa sabbin aikace-aikace a aikin injiniyan halittu da makamashi mai dorewa, cellulose na halitta ya kasance abu mai mahimmanci.Fahimtar tsarinsa, kaddarorinsa da asalinsa yana da mahimmanci don buɗe cikakkiyar damar wannan polymer mai ban mamaki don magance ƙalubale da buƙatun duniya mai tasowa cikin sauri.
