Puas yog cellulose yog ntuj lossis hluavtaws polymer?

Celluloseyog ib tug natural polymer, ib qho tseem ceeb ntawm lub cell phab ntsa hauv cov nroj tsuag. Nws yog ib qho ntawm feem ntau cov organic tebchaw nyob rau hauv lub ntiaj teb thiab ua hauj lwm raws li ib yam khoom siv nyob rau hauv cov nroj tsuag lub nceeg vaj. Thaum peb xav txog cellulose, peb feem ntau koom nrog nws muaj nyob hauv ntoo, paj rwb, ntawv, thiab ntau yam khoom siv los ntawm cov nroj tsuag.

Cov qauv ntawm cellulose muaj cov hlua ntev ntawm cov piam thaj molecules txuas ua ke los ntawm beta-1,4-glycosidic bonds. Cov chains no yog teem rau hauv ib txoj kev uas tso cai rau lawv tsim muaj zog, fibrous lug. Qhov tshwj xeeb kev npaj ntawm cov chains no muab cellulose nws cov cuab yeej zoo kawg nkaus, ua rau nws yog ib qho tseem ceeb hauv kev muab kev txhawb nqa rau cov nroj tsuag.

Cov txheej txheem ntawm cellulose synthesis nyob rau hauv cov nroj tsuag muaj cov enzyme cellulose synthase, uas polymerizes qabzib molecules mus rau hauv chains ntev thiab extrudes lawv mus rau hauv lub cell phab ntsa. Cov txheej txheem no tshwm sim nyob rau hauv ntau hom ntawm cov nroj tsuag, pab txhawb lub zog thiab rigidity ntawm cov ntaub so ntswg.

Vim nws cov nplua nuj thiab cov khoom tshwj xeeb, cellulose tau pom ntau daim ntawv thov dhau ntawm nws lub luag haujlwm hauv cov nroj tsuag biology. Kev lag luam siv cellulose rau kev tsim cov ntawv, textiles (xws li paj rwb), thiab qee hom biofuels. Tsis tas li ntawd, cellulose derivatives zoo li cellulose acetate thiab cellulose ethers yog siv nyob rau hauv ntau yam khoom, nrog rau cov kws, zaub mov additives, thiab coatings.

Thaumcellulosenws tus kheej yog ib tug natural polymer, tib neeg tau tsim cov txheej txheem los hloov thiab siv nws nyob rau hauv ntau txoj kev. Piv txwv li, tshuaj kho mob tuaj yeem hloov kho nws cov khoom kom nws haum rau cov kev siv tshwj xeeb. Txawm li cas los xij, txawm tias nyob rau hauv cov ntaub ntawv hloov kho, cellulose khaws nws cov hauv paus hauv paus hauv paus, ua rau nws muaj ntau yam thiab muaj txiaj ntsig cov khoom siv hauv ob qho tib si ntuj thiab tsim qauv.
