-D-glucose and -D-glucose are not…..to each other
In carbohydrate chemistry, isomers differing in their configuration at anomeric carbon(C-1 in aldoses and C-2 in ketoses) are a pair of anomers;
Anomers are C-1 epimers in aldoses whereas C-2 epimers in ketoses;
Anomers and epimers are diastereomers but not enantiomers;
They differ in their configuration only at one carbon so they are not mirror images;
