Qhov sib txawv tseem ceeb ntawm cellobiose thiab cellulose yog cellobiose yog disaccharide, whereas cellulose yog polysaccharide.
Cellobiose thiab cellulose yog cov carbohydrate compounds. Peb tuaj yeem faib cov carbohydrates rau hauv ntau pawg xws li monosaccharides, disaccharides thiab polysaccharides, nyob ntawm tus qauv thiab qhov nyuaj ntawm cov carbohydrates. Ib qho monosaccharide yog cov suab thaj yooj yim, thaum lub disaccharide yog kev sib xyaw ntawm ob lub monosaccharides thiab polysaccharide yog kev sib xyaw ntawm ntau cov monosaccharide units.
Cellobiose yog dab tsi?
Cellobiose yog cov carbohydrate nrog cov tshuaj formula C12H22O11Peb tuaj yeem categorize nws li disaccharide. Nws yog qhov txo cov suab thaj. Qhov ntawd txhais tau tias; cellobiose tuaj yeem ua raws li tus neeg sawv cev txo qis vim tias nws muaj pawg ketone dawb hauv nws cov qauv. Cellobiose muaj ob lub beta-glucose molecules txuas ntawm beta 1-4 glycosidic linkage. Txawm li cas los xij, nws txawv ntawm m altose vim tias kev teeb tsa ntawm glycosidic daim ntawv cog lus sib txawv. Peb tuaj yeem hydrolyze cov ntsiab lus no rau hauv qabzib los ntawm kev siv cov tshuaj enzymatic lossis siv tshuaj lom neeg siv cov kua qaub.
Thaum xav txog cov qauv ntawm cellobiose, muaj yim pawg cawv dawb nrog rau pawg acetal thiab pawg hemiacetal. Cov pab pawg no muab cov molecule nrog lub peev xwm los tsim muaj zog intermolecular hydrogen bonds.
Daim duab 01: Cov Qauv Tshuaj ntawm Cellobiose
Peb tuaj yeem tau txais cellobiose los ntawm cellulose lossis cellulose-muaj cov ntaub ntawv xws li ntawv, paj rwb, thiab lwm yam. Ntawm no, peb xav tau enzymatic lossis acidic hydrolysis ntawm cov ntaub ntawv kom tau cellobiose los ntawm cov ntaub ntawv no. Qhov kev sib xyaw no kuj tseem ceeb hauv kev kuaj pom tus kab mob Crohn, ua qhov taw qhia rau carbohydrates.
Cellulose yog dab tsi?
Cellulose yog cov carbohydrates peb tuaj yeem faib ua polysaccharide thiab nws muaj cov tshuaj formula (C 6 H 10 O 5)n. Nws tuaj yeem muaj ntau pua mus rau txhiab tus D-glucose units, txuas rau ib leeg ntawm beta 1-4 glycosidic bonds. Yog tias peb tsim lossis cais tawm ntawm qhov chaw, nws zoo li cov hmoov dawb. Cellulose tam sim no yog ib qho tseem ceeb ntawm cov phab ntsa ntawm tes hauv cov nroj tsuag thiab algae. Qee zaum, qee hom kab mob kuj zais cellulose los ua biofilms. Yog li, peb tuaj yeem hais tias cellulose yog cov khoom siv polymer ntau tshaj plaws hauv ntiaj teb.
Daim duab 02: Cov qauv tshuaj ntawm Cellulose
Cellulose yog ib qho tsis muaj ntxhiab thiab tsis muaj xim. Nws yog insoluble hauv dej thiab ntau cov kuab tshuaj organic. Tsis tas li ntawd, nws yog ib qho chiral compound, thiab yog biodegradable ib yam nkaus. Peb tuaj yeem rhuav tshem cellulose rau hauv cov piam thaj los ntawm kev ntxiv cov ntxhia hauv cov kua qaub ntawm qhov kub siab dua. Piv rau cov hmoov txhuv nplej siab, cov khoom sib xyaw no yog crystalline heev, thiab nws tuaj yeem hloov pauv los ntawm crystalline mus rau cov qauv amorphous thaum cua sov.
Thaum xav txog cov ntawv thov ntawm cellulose, nws yog siv los tsim cov ntawv thiab ntawv. Peb kuj tuaj yeem siv nws rau kev tsim cov cellophane thiab rayon. Ntxiv rau cov no, muaj kev tshawb fawb tshawb fawb txog kev hloov pauv ntawm cellulose rau hauv biofuel.
Qhov txawv ntawm Cellobiose thiab Cellulose yog dab tsi?
Cov ntsiab lus cellobiose thiab cellulose feem ntau poob rau hauv thaj chaw ntawm biochemistry. Cov no yog cov carbohydrate compounds. Qhov sib txawv tseem ceeb ntawm cellobiose thiab cellulose yog tias cellobiose yog disaccharide, thaum cellulose yog polysaccharide. Ntxiv mus, cellobiose yog txo cov suab thaj thaum cellulose tsis txo cov suab thaj.
Hauv qab infographic tabulates qhov sib txawv ntawm cellobiose thiab cellulose.
Summary – Cellobiose vs Cellulose
Cellobiose thiab cellulose yog cov carbohydrate compounds. Qhov sib txawv tseem ceeb ntawm cellobiose thiab cellulose yog cellobiose yog disaccharide, thaum cellulose yog polysaccharide. Ntxiv mus, cellobiose yog txo cov suab thaj thaum cellulose tsis txo cov suab thaj.
