Cellulose yog cov dej-insoluble compound uas koom rau hauv kev sib xyaw ntawm cov cell membrane ntawm cov nroj tsuag. Cellulose nws tus kheej yog cov molecule uas loj heev, muaj ntau txhiab phav ib puas yam txuas nrog ua ke los ntawm cov kuab tshuaj, muaj zog heev dua li ntawm cov hmoov txhuv nplej siab.

Cellulose hais txog cov pab pawg ntawm cov fibers uas nyob rau hauv tas li ntawd, pectin, lignin, gelatin thiab mucous tshuaj muaj. Cellulose yog qhov tseem ceeb ntawm cov xovtooj ntawm cov ntoo. Cov nroj tsuag loj muaj 40 txog 70% cellulose, uas muaj ntau tshaj li ib nrab ntawm cov nqi hauv cov pa roj carbon monoxide.

Cellulose yog muaj li ntawm polymers ntawm D thiab b-piam thaj. Kev tawg ntawm cellulose yog qhov tseem ceeb rau lub voj voog cov pa roj carbon monoxide.

Cellulose nws tsis yog tawg yog zom cov enzymes hauv tib neeg lub cev, tab sis qee qhov enzymes hauv lub plab tsim cov enzyme tshwj xeeb - cellulase, uas cov zom cellulose rau cov tshuaj lom uas tau txais qee feem nyob hauv cov qis ntawm txoj hnyuv.

Lub luag haujlwm tseem ceeb ntawm cellulose yog txhawm rau txhaws plab hnyuv peristalsis. Nws muaj cov nyhuv qis dua ntawm cov roj carbohydrate thiab lipid metabolism piv rau pectin, tab sis ntawm qhov tod tes nws muaj qhov ua tau zoo rau kev zais thiab lub cev muaj zog ua haujlwm ntawm txoj hnyuv thiab lub plab. Yog li, cellulose pab txo cov ntshav lipids (triglycerides thiab roj cholesterol) thiab normalizes cov piam thaj tsis pub cuam tshuam hauv cov neeg muaj ntshav qab zib thiab insulin tsis kam.

Qhov chaw ntawm cellulose

Lub softer lub pulp, zoo dua rau lub plab. Nov yog cellulose hauv zaub cog thiab qos yaj ywm feem ntau. Taub dag yog qhov tseem ceeb ntawm cov as-ham thiab cellulose. Lwm yam zaub mov yog khaub noom, cereals, legumes, zaub xas lav, zaub qhwv, txhuv thiab wholemeal qhob cij. Cov txiv hmab txiv ntoo yog cov nplua nuj heev hauv cellulose.

Hauv qee yam khoom lag luam uas ntim cellulose kuj tseem muaj lactose, uas yog xav tau kom muaj kev tshuav nyiaj li cas hauv cov plab hnyuv muaj. Cov no yog zucchini, txiv puv luj, txiv ntaub ntoo, tshiab thiab qhuav apricots, asparagus, currants dub, blueberries, zaub cob pob, zaub xas lav, zaub paj dawb thiab turnips. Los ntawm kev noj cov khoom no koj yuav tsis tsuas tau txais cov tsim nyog ntawm cellulose, tab sis koj tseem yuav tiv thaiv cov tsos mob ntawm dysbacteriosis.

Cov txiaj ntsig ntawm cellulose

Cellulose yog qhov tseem ceeb tshaj plaws rau kev ua haujlwm ntawm lub plab thiab rau lub cev muaj zog ua haujlwm ntawm txoj hnyuv. Nws kuj tseem ceeb rau cov kab ke ncig. Cellulose khi rau cov roj (cholesterol) thiab tiv thaiv nws qhov nqus mus rau hauv cov hnyuv, thiab chaw pib mus rau hauv cov hlab ntshav.

Ib qho txiaj ntsig zoo kawg ntawm cellulose yog tias nws tau ua tiav qeeb hauv lub cev, thiab cov khoom lag luam uas muaj nws muaj cov calories tsawg - nws ua rau lub siab xav li tsis muaj noj ntau yam calories.

Muaj cov cellulose hauv cov zaub mov yog qhov tseem ceeb rau kev tswj kev noj qab haus huv thiab pom lub cev qhov hnyav. Nws muaj cov nyhuv tshuaj tsis haum vim tias nws pab ua kom cov kua ntsev thiab dej paug. Ntawm qhov tod tes, nws yog qhov chaw ntawm cov poov tshuaj thiab cov vitamins tseem ceeb.

Khoom noj cellulose muaj txiaj ntsig zoo heev rau kev tawm tsam cem quav. Tus mob no tsis tsuas yog tsis kaj siab xwb tab sis kuj tseem ua rau muaj kev phom sij rau lub cev. Los ntawm kev noj cov zaub mov tsis tu ncua, peristalsis yog txhim kho thiab cov hnyuv tawm.

Ua mob los ntawm cellulose

Zaub cellulose hauv vaj zaub yog mos, tab sis qee kis ua rau lub plab zom zaub mov. Zaub pob, dib thiab zaub xas lav muaj rougher celluloseuas tuaj yeem ua rau cov tsos mob tsis zoo - tsam plab, mob plab, roj thiab mob plab ntxiv. Khoom noj cellulose kuj tseem tsis pom zoo rau qee qhov mob plab. Yog tias koj pom kev voos lossis tsis xis nyob hauv plab tom qab noj zaub mov cellulose, nws yog qhov zoo tshaj plaws los hloov koj cov khoom noj rau ob peb lub lis piam thiab sab laj nrog kws kho mob.
