(3 ntsiab lus) D-Mannose yog C2-epimer ntawm D-glucose.
Qhov twg hauv qab no yog C-2 Empire ntawm D-glucose?
D-Mannose yog epimer ntawm qabzib ntawm C-2 txoj haujlwm. D-Galactose yog ib qho epimer ntawm qabzib vim qhov sib txawv ntawm ob lub suab thaj yog qhov teeb tsa ntawm C-4 txoj haujlwm.
Qhov twg hauv qab no yog ib qho epimer ntawm D-glucose?
D-Mannose yog ib qho epimer ntawm D-glucose vim tias ob lub suab thaj sib txawv tsuas yog hauv kev teeb tsa ntawm C-2. Thaum lub molecule xws li qabzib hloov mus rau hauv daim ntawv cyclic, nws tsim ib qho chaw tshiab chiral ntawm C-1. Cov pa roj carbon atom uas tsim cov chaw tshiab chiral (C-1) hu ua anomeric carbon.
Lub npe ntawm C-4 epimer ntawm D-glucose yog dab tsi?
D-Galactose yog C-4 epimer ntawm D-glucose.
YPuas D-glucose yog epimer?
Epimers yog cov carbohydrates uas sib txawv hauv ib txoj haujlwm rau kev tso kawm ntawm -OH pawg. Cov piv txwv zoo tshaj yog rau D-glucose thiab D-galactose. … Qhov sib txawv ntawd ua rau D-glucose thiab D-galactose epimers. Lawv tsis yog enantiomers, lossis diastereomers, lossis isomers, lawv tsuas yog epimers
