Introduction:

Vitamin C, also known as ascorbic acid, is an acidic polyhydroxy compound containing 6 carbon atoms and has a molecular formula of C6H8O6 and a molecular weight of 176.1.

Naturally occurring ascorbic acid has two kinds of L-type and D-type, and the latter has no biological activity. Vitamin C is a colorless, odorless flake crystal that is easily soluble in water and insoluble in organic solvents. When it is stable in acidic environment, oxygen, heat, light and alkaline substances in the air, especially oxidases and trace amounts of copper, iron and other metal ions, can promote its oxidative destruction. Oxygenases are generally found in vegetables, and they are lost to varying degrees during storage. However, the bioflavonoids contained in some fruits can protect their stability.

Vitamin C is similar in structure to glucose and is a polyhydroxy compound. Its two adjacent enol-type hydroxyl groups on the 2nd and 3rd positions in the molecule are easily dissociated to release H+, so it has the property of an acid. ascorbic acid. Vitamin C has a strong reducibility and is easily oxidized into dehydrogenated vitamin C, but its response is reversible, and ascorbic acid and dehydroascorbic acid have the same physiological functions, but if dehydroascorbic acid continues to oxidize, diketo ancient For acid, the reaction is irreversible and completely loses its physiological effect.
