Extended data:
The structure of vitamin C is similar to glucose, and it is a polyhydroxy compound. Two adjacent enolic hydroxyl groups in the second and third positions of its molecule are easily dissociated to release H+, so it has the nature of acid, also known as ascorbic acid.
Vitamin C has strong reducibility and can be easily oxidized to dehydrovitamin C, but its reaction is reversible, and ascorbic acid and dehydroascorbic acid have the same physiological function. However, if dehydroascorbic acid continues to be oxidized to generate diketonate, the reaction will be irreversible and completely lose its physiological efficacy.
