Vitamin C, also known as vitamin C, is a polyhydroxy compound with a chemical formula of C6H8O6. The structure is similar to glucose, and the two adjacent enol hydroxyl groups at the 2nd and 3rd positions in the molecule are easily dissociated and release H+, so it has acid properties, also known as L-ascorbic acid. Vitamin C has strong reducing properties and is easily oxidized to dehydrovitamin C, but its reaction is reversible, and ascorbic acid and dehydroascorbic acid have the same physiological functions, but if dehydroascorbic acid continues to oxidize, diketocorbic acid is formed. Lonic acid reacts irreversibly and completely loses its physiological efficacy.
