function | Vitamin C is similar in structure to glucose. It is a polyhydroxy compound. The two adjacent enol-type hydroxyl groups in the 2nd and 3rd positions of the molecule are easily dissociated to release H+, so they have acid properties. ascorbic acid. Vitamin C has strong reducibility and is easily oxidized to dehydrogenated vitamin C, but its reaction is reversible, and ascorbic acid and dehydroascorbic acid have the same physiological functions, but dehydroascorbic acid continues to oxidize to form diketone Leuconic acid, the reaction is irreversible and completely loses physiological efficacy. |
