Nyob rau hauv sucrose, cov monomers qabzib thiab fructose yog txuas los ntawm ether daim ntawv cog lus ntawm C1 ntawm glucosyl subunit thiab C2 ntawm fructosyl chav tsev. Daim ntawv cog lus hu ua a glycosidic linkage.
Puas sucrose yog Alpha linkage?
Sucrose yog tsim los ntawm cov molecule ntawm qabzib koom nrog molecule ntawm fructose los ntawm α-1, β-2-glycosidic linkage. Nws yog cov suab thaj uas tsis txo qis uas pom muaj nyob hauv qab zib pas nrig thiab qab zib beets.
Qhov twg ntawm qhov txuas hauv qab no pom muaj nyob hauv sucrose?
1-2 glycosidic linkage
Kev sib txuas glycosidic twg muaj nyob hauv sucrose?
Teb tiav: Cov glycosidic txuas tam sim no hauv sucrose yog thawj qhov kev xaiv uas yog C - 1 ntawm \[alpha ]- qabzib thiab C - 2 ntawm \[beta ]- fructose Glycosidic linkage tuaj yeem txhais tau tias yog kev sib txuas ntawm lub taub hau. Cov monomers thiaj li hu ua piam thaj thiab fructose ua tiav qhov kev sib txuas hauv sucrose.
Qhov kev sib txuas twg muaj β 1 → 4 txuas?
Lactose, cov kua mis disaccharide, muaj galactose koom nrog cov piam thaj los ntawm β-1, 4-glycosidic linkage.
