I am not sure what you are asking, but D-glucose and D-fructose are constitutional isomers.
Explanation:
The structures of D-fructose and D-glucose are
They each have the same molecular formula,
But D-fructose has a primary alcohol at
And D-glucose has an aldehyde at
This makes them constitutional isomers, because they have the same formula but a different order of bonding.
Beyond this, we can say that they are both hexoses, but one is a ketohexose and the other is an aldohexose.
Also, D-fructose is levorotatory, but D-glucose is dextrorotatory.
