Epimer: Ib qho ntawm ib khub ntawm stereoisomers uas txawv ntawm qhov kev teeb tsa ntawm ib lub stereocenter. Thaum cov molecule tsuas muaj ib lub stereocenter ces cov epimers yog enantiomers.
Dab tsi yog Epimer nrog piv txwv?
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. … Lawv tsis yog enantiomers, los yog diastereomers, los yog isomers, lawv tsuas yog epimers.
Yuav ua li cas hauv qab no ua Epimeric khub?
D- Glucose, D- Mannose
YPuas yog D-glucose thiab D mannose epimers?
Lawv yog hom tshwj xeeb ntawm stereoisomers uas muaj ntau lub stereocenters tab sis txawv ntawm ib leeg los ntawm kev teeb tsa ntawm ib qho chaw stereogenic. Nyob rau hauv cov ntaub ntawv ntawm cov piam thaj thiab mannose, lawv txawv ntawm ib leeg los ntawm kev teeb tsa ntawm C-2 atom. … Yog li ntawd, glucose thiab mannose yog epimers.
Ob lub suab thaj twg yog epimers?
Epimers. Ob lub suab thaj sib txawv hauv kev teeb tsa ntawm ib qho asymmetric carbon atom hu ua epimers. Glucose thiab mannose yog C2 epimers, ribose thiab xylose yog C3 epimers, thiab gulose thiab galactose kuj yog C3 epimers (Daim duab 3).
