Cellulose yog dab tsi thiab nws puas phem rau koj?

Cellulose yog ib tug complex carbohydrate uas yog ib feem ntawm lub cell phab ntsa ntawm cov nroj tsuag. Nws yog tsim los ntawm cov saw ntev ntawm cov piam thaj molecules uas txuas ua ke los ntawm beta-1,4-glycosidic bonds. Cov chains ntawm cov piam thaj molecules yog teem rau hauv ib txoj kab ncaj nraim thiab tuav ua ke los ntawm hydrogen bonds. Qhov no muab cellulose nws lub zog thiab rigidity.

Cellulose yog cov organic ntau tshaj plaws nyob rau hauv lub ntiaj teb, ua li 33% ntawm tag nrho cov nroj tsuag. Nws muaj nyob rau hauv tag nrho cov nroj tsuag cov ntaub so ntswg, tab sis feem ntau yog concentrated nyob rau hauv lub cell phab ntsa ntawm stems, nplooj, thiab keeb kwm. Qee qhov chaw ntawm cellulose nyob rau hauv tib neeg noj zaub mov muaj xws li txiv hmab txiv ntoo, zaub, whole grains, txiv ntseej, thiab noob.

Thaum cellulose tsis phem rau koj, nws yog indigestible los ntawm tib neeg vim beta-1,4-glycosidic bonds uas tuav cov piam thaj molecules ua ke. Tib neeg tsis muaj cov enzyme tsim nyog los rhuav tshem cov ntawv cog lus, yog li cellulose dhau los ntawm lub plab zom mov feem ntau tsis zoo. Qhov no yog vim li cas cellulose feem ntau hu ua kev noj haus fiber ntau.

Txawm hais tias nws indigestibility, cellulose plays lub luag haujlwm tseem ceeb hauv kev tswj kev zom zaub mov. Thaum noj, nws ntxiv ntau rau cov quav thiab pab tiv thaiv cem quav. Nws kuj tseem pab tswj cov ntshav qab zib kom qis los ntawm kev nqus cov piam thaj mus rau hauv cov hlab ntsha.

Ntxiv nrog rau nws cov txiaj ntsig kev noj qab haus huv, cellulose kuj tseem siv rau ntau yam kev lag luam. Ib qho kev siv ntau tshaj plaws ntawm cellulose yog nyob rau hauv kev tsim cov ntawv thiab cov khoom siv ntawv. Cellulose fibers kuj tseem siv rau hauv kev tsim cov khoom siv textiles, plastics, thiab cov khoom siv hauv tsev.

Cellulose kuj tseem siv los ua cov khoom siv hauv ntau cov zaub mov tiav. Vim nws yog indigestible, nws ntxiv bulk rau cov zaub mov tsis muaj calorie ntau ntau. Qhov no tuaj yeem muaj txiaj ntsig zoo rau cov tib neeg uas tab tom sim tswj lawv qhov hnyav lossis txo lawv cov calories kom tsawg.

Txawm li cas los xij, qee tus neeg yuav muaj kev tsis haum plab thaum noj cov cellulose ntau. Qhov no tuaj yeem suav nrog cov tsos mob xws li tsam plab, pa roj, thiab mob plab. Cov tsos mob no feem ntau yog me me thiab ib ntus, thiab tuaj yeem txo tau los ntawm kev txo cov khoom noj muaj fiber ntau.

Zuag qhia tag nrho, cellulose tsis yog phem rau koj, tab sis yog ib qho tseem ceeb ntawm kev noj qab haus huv. Nws muab ntau cov txiaj ntsig kev noj qab haus huv thiab yog ib feem tseem ceeb ntawm kev saib xyuas kev noj qab haus huv. Txawm hais tias qee tus neeg yuav muaj qhov tsis xis nyob hauv plab thaum noj cov cellulose ntau, qhov no feem ntau tsis yog qhov ua rau muaj kev txhawj xeeb. Raws li nrog rau txhua yam kev noj haus, nws yog ib qho tseem ceeb uas yuav tau noj cellulose nyob rau hauv moderation thiab ua ib feem ntawm kev noj zaub mov zoo.
