Anomers yog cyclic monosaccharides lossis glycosides uas yog epimers, sib txawv ntawm ib leeg hauv kev teeb tsa ntawm C-1 yog tias lawv yog aldoses lossis hauv kev teeb tsa ntawm C-2 yog tias lawv yog ketoses. Cov pa roj carbon epimeric hauv anomers hu ua anomeric carbon lossis anomeric center.
Puas yog txhua tus anomers tseem epimers?
Anomers thiab epimers yog ob qho tib si diastereomers, tab sis ib qho epimer yog ib qho stereoisomer uas txawv hauv kev teeb tsa ntawm ib qho chaw stereogenic, thaum lub anomer yog ib qho epimer uas txawv nyob rau hauv configuration ntawm cov acetal/hemacetal carbon.
Dab tsi yog qhov txawv ntawm epimer thiab anomer?
Tus stereoisomers uas txawv ntawm qhov kev teeb tsa ntawm tsuas yog ib qho chiral carbon atom hu ua epimers whereas cov uas txawv hauv configuration ntawm acetal los yog hemiacetal carbon yog hu ua anomers.
Puas yog epimers thiab anomers diastereomers?
Thiab yog tias cov kab mob diastereomers no yog cyclic hemiacetals zoo li qab zib, ces lawv raug cais ua anomers. … Epimers yog diastereomers uas txawv nyob rau hauv lub configuration ntawm xwb ib chiral center. Anomers yog epimers tshwj xeeb siv los ua tus cwj pwm cyclic carbohydrates.
Epimer Anomer yog dab tsi?
Ib anomer yog ib hom geometric variation pom ntawm qee cov atoms hauv carbohydrate molecules. Ib tus epimer yog stereoisomer uas txawv hauv kev teeb tsantawm ib qho chaw stereogenic. Ib tug anomer yog ib tug epimer ntawm lubHemiacetal / hemiketal carbon nyob rau hauv cyclic saccharide, ib qho atom hu ua anomeric carbon.
