Qhov sib txawv tseem ceeb ntawm sucrose thiab qabzib yog sucrose yog disaccharide thaum qabzib yog monosaccharide.
Glucose thiab sucrose yog categorized li carbohydrates. Carbohydrates yog hom ntau tshaj plaws ntawm cov organic molecules hauv ntiaj teb. Lawv yog lub hauv paus ntawm chemical zog rau cov kab mob nyob. Lawv kuj ua haujlwm tseem ceeb ntawm cov ntaub so ntswg. Carbohydrate tuaj yeem muab faib ua peb li monosaccharide, disaccharides thiab polysaccharides.
Sucrose yog dab tsi?
Sucrose yog ib qho disaccharide. Nws yog tsim los ntawm kev sib xyaw ntawm cov piam thaj thiab fructose molecule ntawm glycosidic daim ntawv cog lus. Thaum cov tshuaj tiv thaiv no, ib qho dej molecule raug tshem tawm ntawm ob lub molecules. Sucrose tuaj yeem ua rau hydrolyzed rov qab rau hauv cov molecules pib thaum xav tau. Qhov no yog ib qho disaccharide, uas peb pom feem ntau hauv cov nroj tsuag.
Ntxiv mus, qabzib, uas yog tsim los ntawm photosynthesis nyob rau hauv nplooj, yuav tsum tau muab faib mus rau lwm yam loj hlob thiab khaws cia qhov chaw ntawm cov nroj tsuag. Nws yog thauj nyob rau hauv daim ntawv ntawm sucrose. Yog li ntawd, nyob rau hauv cov nroj tsuag, qabzib hloov mus rau sucrose thiaj li yuav faib lawv. Peb txhua tus paub txog sucrose thaum peb siv nws hauv peb lub neej niaj hnub, ua suab thaj. Sucrose yog dawb crystalline khoom. Nws muaj qab zib thiab yooj yim soluble hauv dej.
Glucose yog dab tsi?
Glucose yog monosaccharide uas muaj rau carbon atoms thiab ib pawg aldehyde. Yog li ntawd, nws yog hexose thiab aldose. Nws muaj plaub pawg hydroxyl thiab muaj cov qauv hauv qab no.
Txawm hais tias nws tau pom tias yog cov qauv linear, cov piam thaj tuaj yeem muaj raws li cov qauv cyclic ib yam nkaus. Qhov tseeb, hauv kev daws teeb meem, feem ntau ntawm cov molecules yog nyob rau hauv cov qauv cyclic. Thaum cov qauv cyclic yog tsim, -OH ntawm carbon 5 yog hloov dua siab tshiab rau hauv ether linkage, kaw lub nplhaib nrog carbon 1. Qhov no tsim ib tug rau-tus tswv cuab lub nplhaib. Lub nplhaib tseem hu ua lub nplhaib hemiacetal vim muaj cov pa roj carbon uas muaj ob qho tib si ether oxygen thiab ib pawg cawv. Vim yog pab pawg dawb aldehyde, qabzib tuaj yeem txo qis. Yog li, nws yog hu ua txo cov suab thaj. Tsis tas li ntawd, cov piam thaj tseem hu ua dextrose vim nws tig lub dav hlau-polarized rau sab xis.
Thaum muaj tshav ntuj, hauv cov nroj tsuag, cov piam thaj yog synthesized siv dej thiab carbon dioxide. Cov piam thaj no khaws cia thiab siv los ua lub zog. Tsiaj txhu thiab tib neeg tau txais cov piam thaj los ntawm cov nroj tsuag. Cov piam thaj hauv tib neeg cov ntshav yog tswj hwm los ntawm homeostasis mechanism. Insulin thiab glucagon cov tshuaj hormones koom nrog hauv cov txheej txheem. Thaum muaj cov piam thaj hauv cov ntshav siab, nws hu ua mob ntshav qab zib. Kev ntsuas ntshav qab zib ntsuas ntsuas cov piam thaj hauv cov ntshav. Muaj ntau txoj hauv kev los ntsuas cov ntshav qabzib.
Qhov txawv ntawm Sucrose thiab Glucose yog dab tsi?
Qhov sib txawv tseem ceeb ntawm sucrose thiab qabzib yog sucrose yog disaccharide thaum qabzib yog monosaccharide. Sucrose yog tsim los ntawm kev sib xyaw ntawm cov piam thaj thiab fructose molecule ntawm glycosidic daim ntawv cog lus. Ntxiv mus, qhov hnyav molecular ntawm sucrose yog siab dua li cov piam thaj. Tsis tas li ntawd, cov tshuaj formula ntawm sucrose yog C12H22O11 thaum cov tshuaj formula ntawm qabzib yog. C6H12O6 Ntxiv mus, sucrose yog cov piam thaj tsis txo qis thaum cov piam thaj yog txo cov suab thaj..
Cov ntaub ntawv hauv qab no-daim duab tabulates ib sab ntawm qhov sib txawv ntawm sucrose thiab qabzib.
Summary – Sucrose vs Glucose
Glucose yog monosaccharide uas muaj rau carbon atoms thiab ib pawg aldehyde. Sucrose yog tsim los ntawm kev sib xyaw ntawm cov piam thaj thiab fructose molecule ntawm glycosidic daim ntawv cog lus. Sucrose yog disaccharide thaum cov piam thaj yog monosaccharide. Tsis tas li ntawd, sucrose yog cov piam thaj tsis txo qis thaum cov piam thaj yog txo cov suab thaj. Yog li, qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm sucrose thiab qabzib.
