Dhexoses
Dhexoses are a class of carbohydrates that are isomers of hexose sugars, meaning they have the same chemical formula (C6H12O6) but differ in the arrangement of their atoms. Specifically, dhexoses are stereoisomers of hexoses and are characterized by the orientation of their hydroxyl groups. In the D-configuration, the hydroxyl group on the penultimate carbon atom (the carbon furthest from the carbonyl group) is on the right side when the sugar molecule is drawn in a Fischer projection.
The most common and biologically significant dhexoses are D-glucose, D-fructose, D-galactose, and D-mannose. D-glucose is the
These dhexoses can exist in linear or cyclic forms. In aqueous solutions, they predominantly form cyclic hemiacetal
