Qhov sib txawv tseem ceeb ntawm m altose thiab isom altose yog tias m altose muaj ob lub qabzib sib koom ua ke ntawm alpha 1-4 daim ntawv cog lus thaum lub isom altose muaj ob chav piam thaj koom ua ke ntawm alpha 1-6 daim ntawv cog lus.
M altose yog ib qho tshuaj tsis haum. Nws txhais tau hais tias nws muaj ob chav suab thaj koom ua ke. Nyob rau hauv cov ntaub ntawv ntawm m altose thiab isom altose, lub qab zib chav tsev yog ib tug qabzib molecule. Yog li ntawd, ob hom disaccharides no txawv ntawm ib leeg raws li kev sib koom ua ke ntawm cov piam thaj hauv ob pawg. Txawm li cas los xij, ob daim ntawv qab zib no txo cov suab thaj.
M altose yog dab tsi?
M altose yog ib qho disaccharide uas muaj ob chav piam thaj koom nrog ib leeg los ntawm kev sib txuas ntawm alpha 1-4. Tsis tas li ntawd, cov molecule no tshwm sim thaum lub sij hawm so ntawm starch los ntawm beta-amylase; Nws tshem tawm ib chav tsev piam thaj ib zaug, tsim cov m altose molecule. Ntxiv mus, nws yog txo cov suab thaj, tsis zoo li lwm cov disaccharide molecules. Qhov no feem ntau yog vim hais tias, lub nplhaib qauv ntawm ib qho ntawm ob lub qabzib molecules tuaj yeem qhib los nthuav qhia cov pab pawg dawb aldehyde, tab sis lwm cov piam thaj tsis tuaj yeem qhib li ntawd vim yog qhov xwm txheej ntawm glycosidic daim ntawv cog lus.
Daim duab 01: Cov qauv tshuaj ntawm M altose
Glucose yog hexose, lub ntsiab lus; nws muaj rau carbon atoms nyob rau hauv lub nplhaib pyranose. Hauv qhov no, thawj cov pa roj carbon atom ntawm ib cov piam thaj molecules txuas mus rau plaub carbon atom ntawm lwm cov piam thaj molecule los tsim 1-4 glycosidic daim ntawv cog lus. Cov enzyme, m altase tuaj yeem rhuav tshem cov qauv ntawm m altose ntawm catalysing hydrolysis ntawm glycosidic daim ntawv cog lus. Cov suab thaj no tshwm sim ua ib feem ntawm m alt thiab tseem muaj nyob rau hauv ntau qhov sib txawv ntawm cov khoom siv hydrolysed ib nrab. Piv txwv li: m altodextrin, pob kws phoov, thiab lwm yam.
Isom altose yog dab tsi?
Y Isom altose yog ib qho disaccharide uas muaj ob chav piam thaj qab zib txuas rau ib leeg los ntawm kev sib txuas ntawm alpha 1-6. Yog li, cov molecule no txawv ntawm m altose molecule vim qhov kev sib txuas no (vim tias m altose muaj alpha 1-4 linkage es tsis yog alpha 1-6 linkage). Ntau precisely, isom altose yog ib qho isomer ntawm m altose. Nws kuj yog txo cov suab thaj.
Daim duab 02: Cov Qauv Tshuaj ntawm Isom altose
Ntxiv mus, cov molecule no tshwm sim thaum peb kho cov m altose syrup siab nrog enzyme transglucosidase (TG). Nws ua rau cov khoom ntawm caramelization ntawm qabzib.
Dab tsi yog qhov zoo sib xws ntawm M altose thiab Isom altose?
- M altose thiab Isom altose txo cov suab thaj
- Kuj, ob qho tib si yog disaccharides.
- Ntxiv mus, ob leeg muaj qab zib.
Qhov txawv ntawm M altose thiab Isom altose yog dab tsi?
M altose yog ib qho disaccharide uas muaj ob chav piam thaj koom nrog ib leeg los ntawm kev sib txuas ntawm alpha 1-4 whereas Isom altose yog ib qho disaccharide uas muaj ob chav piam thaj txuas rau ib leeg los ntawm kev sib txuas ntawm alpha 1-6. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm m altose thiab isom altose. Tsis tas li ntawd, hauv m altose, thawj carbon ntawm ib chav tsev piam thaj khi nrog plaub cov pa roj carbon monoxide ntawm lwm chav tsev qab zib thaum thawj cov pa roj carbon monoxide ntawm ib chav tsev piam thaj khi nrog rau thib rau carbon ntawm lwm chav tsev qab zib hauv isom altose. Yog li, cov qauv tshuaj yog qhov sib txawv loj ntawm m altose thiab isom altose. Qhov tseem ceeb tshaj, isom altose yog isomer ntawm m altose.
Cov hauv qab no infographic suav txog qhov sib txawv ntawm m altose thiab isom altose hauv daim ntawv tabular.
Summary – M altose vs Isom altose
Isom altose yog ib qho isomer ntawm m altose vim tias ob qho tib si no muaj cov qauv tshuaj zoo sib xws nrog qhov sib txawv me ntsis hauv kev sib txuas ntawm ob chav suab thaj. Yog li ntawd, qhov sib txawv tseem ceeb ntawm m altose thiab isom altose yog tias m altose muaj ob chav piam thaj koom nrog ib leeg ntawm alpha 1-4 daim ntawv cog lus thaum isom altose muaj ob chav piam thaj koom nrog ib leeg ntawm alpha 1-6 daim ntawv cog lus.
