Polysaccharides yog ib chav tseem ceeb ntawm biological polymers. Lawv txoj haujlwm hauv cov kab mob muaj sia feem ntau yog cov qauv- lossis kev cia khoom. Cov hmoov txhuv nplej siab (polymer ntawm qabzib) yog siv los ua ib qho chaw cia khoom polysaccharide hauv cov nroj tsuag, pom nyob rau hauv daim ntawv ntawm ob qho tib si amylose thiab branched amylopectin.
YPuas yog polysaccharide yog polymer?
Polysaccharides yog polymersmuaj cov chains ntawm monosaccharide lossis disaccharide units koom nrog glycosidic bonds nrog ntau tus C (piv txwv li rau rau hexose xws li qabzib).
YPuas yog polysaccharide monomer lossis polymer?
Polysaccharides, lossis glycans, yog polymers suav nrog ntau pua monosaccharide monomers txuas ua ke los ntawm glycosidic bonds. Lub zog-storage polymers hmoov txhuv nplej siab thiab glycogen yog cov piv txwv ntawm polysaccharides thiab tag nrho cov tsim los ntawm ceg chains ntawm qabzib molecules.
Puas yog disaccharide yog polymer?
A disaccharide yog carbohydrate polymertsim los ntawm ob lub suab thaj monomers (monosaccharides) uas tau koom nrog glycosidic daim ntawv cog lus tsim los ntawm cov tshuaj tiv thaiv condensation. Disaccharides yog cov ntaub ntawv yooj yim tshaj plaws ntawm polysaccharides.
YYuav ua li cas cov polymers hu ua polysaccharides?
Raws li lub npe txhais tau hais tias, polysaccharides yog cov loj molecular hnyav molecules tsim los ntawm kev koom nrog monosaccharide units ua ke los ntawm glycosidic bonds. Lawv qee zaum hu ua glycans. CovCov ntsiab lus tseem ceeb tshaj plaws hauv chav kawm no, cellulose, starch thiab glycogen yog tag nrho polymers ntawm qabzib.
