Dextrose vs Glucose
Glucose thiab dextrose yog categorized li carbohydrates. Carbohydrates yog ib pawg ntawm cov tebchaw uas txhais tau tias "polyhydroxy aldehydes thiab ketones lossis cov khoom uas hydrolyze kom tawm los polyhydroxy aldehydes thiab ketones." 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. Tsis tas li ntawd xwb, lawv ua haujlwm tseem ceeb ntawm cov ntaub so ntswg. Carbohydrate tuaj yeem muab faib ua peb yam xws li monosaccharides, disaccharides thiab polysaccharides. Monosaccharides yog hom carbohydrate yooj yim tshaj plaws. Glucose thiab dextrose yog monosaccharides. Monosaccharides raug cais raws li, • Tus naj npawb ntawm carbon atoms tam sim no nyob rau hauv lub molecule
• Seb lawv muaj aldehyde lossis keto pawg
Yog li ntawd, ib qho monosaccharide nrog rau 6 carbon atoms hu ua hexose. Yog hais tias muaj tsib carbon atoms, ces nws yog ib tug pentose. Tsis tas li ntawd, yog tias cov monosaccharide muaj ib pawg aldehyde, nws hu ua aldose. Ib qho monosaccharide nrog pawg keto hu ua ketose.
YGlucose
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, feem ntau ntawm cov molecules yog nyob rau hauv cov qauv cyclic. Thaum ib tug cyclic qauv tsim, lub -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 lub nplhaib qauv. Lub nplhaib tseem hu ua lub nplhaib hemiacetal, vim muaj cov pa roj carbon monoxide uas muaj 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 hnub ci, hauv cov nroj tsuag chloroplasts, qabzib 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 no. 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.
Dextrose
Hauv cov ntsiab lus dav dav, dextrose yog tib yam li qabzib. Nws muaj tib cov qauv molecular. Tab sis thaum peb xav txog stereochemistry ntawm molecules, dextrose yog qhov peb hu ua D-glucose. Enantiomers yog ib hom tshwj xeeb ntawm isomerism pom nyob rau hauv khub ntawm cov qauv uas yog daim iav duab ntawm ib leeg. Ob lub qauv raug xaiv raws li D qab zib thiab L qab zib. Ob hom no txawv vim txoj kev uas lawv tig lub dav hlau polarized teeb. Dextrose tig dav hlau polarized teeb rau sab xis. Yog li ntawd, rau cov piam thaj, muaj ob enantiomers li D thiab L, tab sis D-glucose los yog dextrose yog ib tug ntau ntawm tib neeg.
Dab tsi yog qhov txawv ntawm Glucose thiab Dextrose?
• Dextrose tseem hu ua D-glucose.
• L- Glucose thiab dextrose yog daim iav duab ntawm ib leeg.
• Dextrose txawv ntawm qabzib vim nws tig lub dav hlau polarized rau sab xis.
• Dextrose yog hom qabzib ntau hauv cov xwm txheej.
