Qhov sib txawv tseem ceeb ntawm sorbitol thiab xylitol yog tias sorbitol yog cov khoom qab zib uas siv ntau tshaj plaws hauv cov pos hniav uas tsis muaj qab zib vim nws tsis tshua kim, qhov xylitol muaj txiaj ntsig zoo li piam thaj hloov hauv cov pos hniav tsis muaj qab zib, khoom qab zib, thiab mints tab sis nws yog kim tshaj sorbitol.
cov khoom qab zib tsis muaj qab zib, cov pos hniav, thiab mints tau nrov niaj hnub no vim cov khoom no tsis ua kom cov ntshav qab zib nce siab zoo li cov tshuaj muaj piam thaj.
YSorbitol yog dab tsi?
Sorbitol tuaj yeem txhais tau tias yog cawv qab zib uas muaj qab zib. Cov tshuaj no feem ntau tshwm sim hauv cov qos yaj ywm starch. Nws tuaj yeem maj mam metabolize hauv tib neeg lub cev. Peb tuaj yeem tau txais cov khoom no los ntawm kev txo cov piam thaj. Hauv cov txheej txheem txo qis no, pawg aldehyde ntawm cov piam thaj hloov mus rau hauv pawg cawv thawj. Yog li, sorbitol yog cawv. Sorbitol tshwm sim raws li qhov tshwm sim tshwm sim, piv txwv li. Hauv cov txiv apples, pears, txiv duaj, thiab lwm yam. Txawm li cas los xij, peb feem ntau tau txais sorbitol los ntawm qos yaj ywm starch.
Thaum ua ke, sorbitol zoo li cov hmoov dawb crystalline. Txoj hauv kev tseem ceeb ntawm kev tsim khoom yog qhov txo cov piam thaj hauv cov tshuaj uas cov aldehyde tau hloov mus rau hauv pawg cawv. Cov tshuaj tiv thaiv no yuav tsum tau NADH thiab tshwm sim nyob rau hauv lub xub ntiag ntawm ib tug catalyst - aldose reductase. Kev txo cov piam thaj yog ib txoj hauv kev ntawm polyol ntau lawm hauv cov piam thaj metabolism.
Daim duab 01: Sorbitol Molecule
Muaj ntau daim ntawv thov ntawm sorbitol: ua cov khoom qab zib, ua laxative, raws li cov kab mob kab lis kev cai, hauv kev kho mob hyperkalemia, hauv kev tsim cov tshuaj mos gel, thiab lwm yam. Sorbitol kuj tseem muaj txiaj ntsig hauv kev lag luam tshuaj pleev ib ce ua cov tshuaj humectant thiab ua cov thickener. Tsis tas li ntawd, muaj ntau yam kev siv sorbitol, xws li kev tsim cov roj foob pob hluav taws, tsim cov khoom siv biomass, thiab lwm yam.
YXylitol yog dab tsi?
Xylitol tuaj yeem raug hu ua tshuaj lom neeg muaj cov mis C2H12O5. Nws yog ib qho stereoisomer thiab tshwm sim raws li cov xim tsis muaj xim lossis dawb crystalline khoom uas yog dej-soluble. Xylitol tuaj yeem muab faib ua polyalcohol lossis qab zib cawv (ib qho alditol). Nws yog feem ntau pab tau raws li cov khoom noj ntxiv los hloov cov suab thaj hauv cov zaub mov thiab tshuaj. Yog li ntawd, nws yog lub npe hu ua ib tug qab zib substituent.
Daim duab 02: Xylitol Qab Zib Crystals
Xylitol yog ib qho tshwm sim ntawm cov organic compound (hauv me me) hauv plums, strawberries, cauliflower, taub dag, thiab lwm yam. Tsis tas li ntawd, tib neeg thiab ntau tus tsiaj kuj ua cov lej ntawm xylitol thaum lub sijhawm metabolism ntawm carbohydrates. Xylitol yog ib qho achiral compound. Qhov ntawd txhais tau tias nws muaj lub dav hlau ntawm symmetry.
Kev tsim khoom lag luam ntawm xylitol pib nrog lignocellulosic biomass los ntawm xylan yog rho tawm. Cov khoom siv raw biomass tuaj yeem siv tau suav nrog ntoo tawv, ntoo mos, cov khoom siv pov tseg los ntawm kev ua cov nplej, thiab lwm yam. Xylan yog ib qho polymer uas peb tuaj yeem hydrolyze rau hauv xylose, uas tom qab ntawd catalytically hydrogenated rau hauv xylitol. Hom kev hloov pauv no hloov cov piam thaj xylose rau hauv cov cawv thawj, xylitol.
Muaj ntau daim ntawv thov xylitol ua cov piam thaj hloov pauv. Cov khoom lag luam suav nrog tshuaj, tshuaj noj, khoom noj khoom haus, tshuaj txhuam hniav, zom cov pos hniav, thiab lwm yam. Tab sis nws tsis yog ib qho khoom qab zib hauv tsev. Qhov tseem ceeb tshaj, qhov sib xyaw no muaj qhov cuam tshuam tsis zoo rau cov ntshav qab zib vim xylitol ua rau cov metabolism hauv nws tus kheej ntawm insulin.
Qhov txawv ntawm Sorbitol thiab Xylitol yog dab tsi?
Qhov sib txawv tseem ceeb ntawm sorbitol thiab xylitol yog tias sorbitol yog cov khoom qab zib uas siv ntau tshaj plaws hauv cov pos hniav vim nws tsis tshua muaj nqi, qhov xylitol muaj txiaj ntsig zoo li piam thaj hloov hauv cov pos hniav tsis muaj qab zib, khoom qab zib, thiab mints tab sis Nws kim dua sorbitol.
Cov hauv qab no qhia txog qhov sib txawv ntawm sorbitol thiab xylitol hauv daim ntawv teev npe rau ib sab ntawm kev sib piv.
Summary – Sorbitol vs Xylitol
Sorbitol tuaj yeem txhais tau tias yog cawv qab zib uas muaj qab zib, thiab cov tshuaj no tshwm sim hauv cov qos yaj ywm starch. Xylitol tuaj yeem raug hu ua tshuaj lom neeg muaj cov mis C2H12O5. Qhov sib txawv tseem ceeb ntawm sorbitol thiab xylitol yog tias sorbitol yog cov khoom qab zib tshaj plaws uas siv hauv cov pos hniav tsis muaj qab zib vim nws qhov tsis tshua muaj nqi, thaum xylitol muaj txiaj ntsig zoo li cov piam thaj hloov hauv cov pos hniav tsis muaj piam thaj, khoom qab zib, thiab mints tab sis nws kim dua. sorbitol.
