If glucose is an aldose sugar why does it not react with sodium hydrogen sulphite?

Glucose is an aldose sugar, meaning it contains an aldehyde group. However, it does not react with sodium hydrogen sulfite because the aldehyde group can form a stable hemiacetal structure with the hydroxyl groups in glucose, preventing the free aldehyde from being available for reaction. Additionally, in solution, glucose exists predominantly in its cyclic form, which further reduces its reactivity with sodium hydrogen sulfite.
