Anomerism of D-glucose
Anomerism of D-glucose
An anomer is a stereoisomer that differs only in configuration at the hemiacetal carbon. This Demonstration shows the two anomers obtained when the D-glucose, through a hemiacetal formation, can lead to two possible outcomes: -D-glucose or -D-glucose. In "alpha" or "beta," the molecules are represented with a standard color code (red for oxygen, black for carbon and white for hydrogen). In "alpha-ring formation focus" and "beta-ring formation focus," a different color code is used, shifting the attention more onto the atoms responsible for the ring formation; select the "condensation focus" control to see only the functional groups.

Snapshot 3: -D-glucose formation highlighting only the functional groups involved: the anomer differs from the one by the position of two hydrogens (colored in brown) that are in opposite directions, considering the plane formed by the ring
