Yenziwe Ngantoni ICellulose?

I-cellulose yi-polysaccharide, oku kuthetha ukuba yi-carbohydrate eyinkimbinkimbi eyenziwe ngamatyathanga amade eemolekyuli zeswekile. Ngokukodwa, i-cellulose iqulunqwe ngamayunithi aphindaphindayo eemolekyuli zeglucose ezidityaniswe kunye nge-β (1→ 4) iibhondi ze-glycosidic. Eli lungiselelo linika i-cellulose isakhiwo sayo se-fibrous.

I-Cellulose iyona nxalenye yesakhiwo seendonga zeseli kwizityalo, ukubonelela ngokuqina, amandla, kunye nenkxaso kwiiseli zezityalo kunye nezicubu. Ininzi kwizinto ezisekelwe kwizityalo ezifana nemithi, umqhaphu, i-hemp, iflakisi kunye nengca.

I-chemical formula ye-cellulose yi (C6H10O5) n, apho i-n imele inani leeyunithi ze-glucose kwi-polymer chain. Ubume obuchanekileyo kunye neepropati zeselulosi zinokuhluka ngokuxhomekeka kwizinto ezifana nomthombo we-cellulose kunye neqondo le-polymerization (oko kukuthi, inani leeyunithi ze-glucose kwi-polymer chain).

I-Cellulose ayinyibiliki emanzini kunye neninzi ye-solvents yezinto eziphilayo, ezinegalelo ekuzinzeni nasekuzinzeni kwayo. Nangona kunjalo, inokwahlulwa ibe ziimolekyuli zayo zeglucose ngokusebenzisa iinkqubo ze-enzymatic okanye iikhemikhali ze-hydrolysis, ezisetyenziswa kwizicelo ezahlukeneyo zemizi-mveliso, ezinje ngokwenziwa kwephepha, ukuvelisa amalaphu, ukuveliswa kwe-biofuel, kunye nokulungiswa kokutya.
