Qhov sib txawv tseem ceeb ntawm trehalose thiab m altose yog tias trehalose muaj 1, 1-glycosidic linkage, whereas m altose muaj 1, 4-glycosidic linkage.
Ob leeg trehalose thiab m altose yog cov carbohydrates uas muaj ob lub qabzib ua ke los ntawm glycosidic bonds. Yog li ntawd, lawv raug hu ua disaccharides - ua los ntawm ob chav monosaccharide.
Trehalose yog dab tsi?
Trehalose yog cov suab thaj uas muaj ob chav alpha qabzib ua ke ntawm 1, 1-glycosidic daim ntawv cog lus. Synonyms rau trehalose yog mycose thiab tremalose. Cov carbohydrates no yog lub zog rau qee cov kab mob fungi, kab mob thiab cov tsiaj tsis muaj zog. Cov suab thaj no zoo li dawb orthorhombic crystals.
Trehalose yog cov piam thaj tsis txo qis. Vim yog 1, 1-alpha glycosidic daim ntawv cog lus, cov suab thaj no tiv taus acid hydrolysis heev. Qhov no ua rau cov piam thaj ruaj khov ntawm qhov kub thiab txias. Nws yog dej-soluble tsawg dua piv rau sucrose. Muaj ob hom trehalose li anhydrous trehalose thiab dihydrated trehalose. Ntawm lawv, daim ntawv anhydrous tau nkag siab nrog cov dej noo, ua rau daim ntawv dihydrated. Ntxiv mus, trehalose ncaj qha reacts nrog nucleic acids xws li DNA, tsim stabilized ib leeg-strand nucleic acid daim ntawv.
Daim duab 01: Tus Qauv ntawm Trehalose
Lub enzyme hu ua trehalase tuaj yeem ua rau trehalose sai sai rau hauv cov piam thaj hauv cov hnyuv mucosa. Tsis tas li ntawd, nws muaj txiaj ntsig tsawg heev rau cov ntshav qab zib piv rau cov piam thaj. Qhov qab zib kuj qis dua sucrose. Qhov tseem ceeb tshaj, trehalose tuaj yeem txo qhov chaw khov ntawm cov zaub mov, yog li, nws yog ib qho tseem ceeb hauv cov khoom noj khov xws li khov khov.
M altose yog dab tsi?
M altose yog ib qho disaccharide uas muaj ob chav alpha qabzib ua ke 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. Nws yog qhov txo cov suab thaj, tsis zoo li lwm cov disaccharide molecules. Qhov no feem ntau yog vim lub nplhaib qauv ntawm ib qho ntawm ob lub qabzib molecules tuaj yeem qhib los nthuav qhia cov pab pawg dawb aldehyde thaum lwm cov piam thaj tsis tuaj yeem qhib zoo li ntawd vim qhov xwm txheej ntawm glycosidic daim ntawv cog lus.
Daim duab 02: Cov qauv ntawm M altose
Glucose yog hexose, txhais tau tias nws muaj rau cov pa roj carbon atom 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. Lub 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.
Qhov txawv ntawm Trehalose thiab M altose yog dab tsi?
Ob leeg trehalose thiab m altose yog disaccharides uas muaj ob chav alpha qabzib. Qhov sib txawv tseem ceeb ntawm trehalose thiab m altose yog tias trehalose muaj 1, 1-glycosidic linkage, thaum m altose muaj 1, 4-glycosidic linkage. Ntxiv mus, trehalose yog ib qho tsis txo cov suab thaj, thaum m altose yog txo cov suab thaj.
Tsis tas li ntawd, trehalose yog tsim los ntawm qee cov kab mob thiab cov kab mob ua lub zog, thaum m altose tsim thaum lub sij hawm tawg ntawm cov hmoov txhuv nplej siab los ntawm beta-amylase. Thaum txiav txim siab txog kev tawg ntawm cov suab thaj no, trehalose tawg los ntawm kev ua ntawm enzyme trehalase hauv plab hnyuv mucosa, thaum m altose tawg los ntawm kev ua ntawm enzyme m altase hauv plab.
Cov ntawv qhia hauv qab no qhia txog qhov sib txawv ntawm trehalose thiab m altose.
Summary – Trehalose vs M altose
Ob leeg trehalose thiab m altose yog disaccharides uas muaj ob chav alpha qabzib. Qhov sib txawv tseem ceeb ntawm trehalose thiab m altose yog tias trehalose muaj 1, 1-glycosidic linkage, whereas m altose muaj 1, 4-glycosidic linkage.
