Starch ( a polymer ntawm qabzib ) yog siv los ua ib qho chaw cia khoom polysaccharide hauv cov nroj tsuag, pom nyob rau hauv daim ntawv ntawm amylose thiab branched amylopectin. Nyob rau hauv cov tsiaj, cov structurally zoo li piam thaj polymer qabzib polymer Structure. Glucans yog polysaccharides muab los ntawm cov piam thaj monomersCov monomers yog txuas los ntawm glycosidic bonds. Plaub hom piam thaj-raws li polysaccharides muaj peev xwm: 1, 6- (starch), 1, 4- (cellulose), 1, 3- (laminarin), thiab 1, 2-bonded glucans. https://en.wikipedia.org › wiki › Glucan

yog cov glycogen densely branched, qee zaum hu ua "tsiaj starch".
YPuas yog hmoov txhuv nplej siab yog monosaccharide disaccharide lossis polysaccharide?
Glucose, galactose, thiab fructose yog cov monosaccharides, thaum cov disaccharides muaj xws li lactose, m altose, thiab sucrose. Cov hmoov txhuv nplej siab thiab glycogen, piv txwv ntawm polysaccharides, yog cov ntaub ntawv khaws cia ntawm cov piam thaj hauv cov nroj tsuag thiab tsiaj txhu, feem. Cov saw hlau ntev polysaccharide tuaj yeem txiav los yog tsis muaj ceg.
Dab tsi yog starches lossis polysaccharides?
Starch yog a polysaccharide suav nrog cov piam thaj monomers koom nrog α 1, 4 linkages. Daim ntawv yooj yim tshaj plaws ntawm cov hmoov txhuv nplej siab yog linear polymer amylose; amylopectin yog cov ceg ntoo.
Puas yog hmoov txhuv nplej siab Tsuas yog polysaccharide?
Polysaccharides yog cov polymers loj heev uas muaj li kaum rau txhiab tus monosaccharides koom ua ke los ntawm glycosidic linkages. Peb qhov ntau tshaj polysaccharides yog hmoov txhuv nplej siab, glycogen, thiab cellulose.
Vim li cas cov hmoov txhuv nplej siab zoo dua qabzib?
Starch zoo dua qabzib rau cia vim nws tsis soluble… Ob qho qabzib thiab hmoov txhuv nplej siab tuaj yeem hloov mus ua lwm yam khoom. Cov no tuaj yeem siv rau lub zog, kev loj hlob thiab lwm yam khoom khaws cia. Ib tsob nroj kuj tsim cov pa oxygen ua cov khoom pov tseg ntawm photosynthesis.
