Polysaccharides muaj ntau cov monosaccharide units sib koom ua ke los ntawm a series ntawm glycosidic bonds Txhua chav ua haujlwm ob leeg ua acetal (lossis ketal) chaw los tsim ib daim ntawv cog lus glycosidic thiab raws li cawv los tsim lwm daim ntawv cog lus glycosidic rau cov neeg nyob sib ze monosaccharides.
Yuav ua li cas polysaccharides tsim los ntawm monosaccharide?
Txhua glycosidic txuas yog tsim nrog tshem tawm cov dej molecule ntawm ob monosaccharides; Qhov no ua rau polysaccharides condensation polymers. … Hydrolysis yog kev tawg ntawm daim ntawv cog lus los ntawm kev sib ntxiv ntawm cov dej molecule thoob plaws nws.
Yuav ua li cas polysaccharides tsim?
Polysaccharides yog tsim thaum lub cev qhuav dej tshwm sim ntawm ntau tus monosaccharides. Amylose (hauv qab) yog polysaccharide muaj li ntawm 60 thiab 300 qabzib units.
Yuav ua li cas monosaccharides tsim?
A monosaccharide feem ntau hloov los ntawm acyclic (qhib-chain) daim ntawv mus rau a cyclic daim ntawv, los ntawm cov tshuaj tiv thaiv nucleophilic ntxiv ntawm pawg carbonyl thiab ib qho ntawm cov hydroxyl ntawm tib yam. molecule. Cov tshuaj tiv thaiv tsim ib lub nplhaib ntawm carbon atoms kaw los ntawm ib tug bridging oxygen atom.
Nruab ntawm polysaccharide yog dab tsi?
Polysaccharides yog cov biomacromolecules complex uas ua los ntawm cov saw hlau monosaccharides. Cov ntawv cog lus uas tsim cov saw hlau no yog cov ntawv cog lus glycosidic. Feem ntau pom cov monomer units hauv polysaccharides yog glucose, fructose, mannose thiab galactose uas yog cov suab thaj yooj yim.
