How do epimers differ from anomers ? |
| Answer» Solution :Carbohydrates which differ in configuration at the glycosidic carbon (i.e.,`C_1` in aldoses and `C_2` in ketoses) are called anomers while those which differ in configuration at any carbon other than glycosidic carbon are called EPIMERS. For example , `alpha`-D- glucose and `beta`-D-glucose are anomers since they differ in configuration at `C_1` (glycosidic carbon) while glucose and mannose are called epimers since they differ in configuration at `C_2` (other than the glycosidic carbon `C_1`). In other words, glucose and MANOSE are `C_2` -epimers. SIMILARLY , we can SHOW that glucose and galactose are `C_4` -epimers since they differ in configuration only at `C_4`. | |
