Vitamin C is widely known as the vitamin whose deficiency causes scurvy in humans. It is is a vital product of our food additives and food ingredients. Of our food additives and food ingredients, Vitamin C has won a high reputation in China and foreign countries.

Main physiological functions of Vitamin C:
1. Vitamin C plays an important role in the biosynthesis of bone collagen, which can accelerate the healing of wounds.
2. Vitamin C can promote the metabolism of tryptophan and tyrosine, prolonging the life of the body.
3. Vitamin C can improve the utilization of the iron, calcium and folic acid.
4. Vitamin C can improve the metabolism of fats, lipoid, and especially cholesterol, which can prevent cardiovascular disease.
5. Vitamin C also can accelerate the growth of bones and teeth, preventing the bleeding of gums.
6. Vitamin C also can enhance body's anti-stress and immunity against the outside environment.


Most of the biological functions of vitamin C are determined by its unique structure. Vitamin C has a molecular formula of C6H8O6 and has two active hydroxyl groups in its lactone ring structure which are readily ionised (pKa 11.6 and 4.2 respectively) to produce ASC and DHA, which can be reduced to ASC in a series of enzymatic reactions, thus making ASC a natural antioxidant, of which the reduced glutathione (GSH) reaction is the most representative. ) dependent DHA reductase-mediated reactions are the most representative.


Collagen synthesis

Collagen is found mainly in the skin, bones, internal organs and other parts of the body and maintains the morphology of the skin and other organs. To facilitate the cross-linking of collagen molecules and to ensure the structural integrity of the tissue, collagen-proline-4-hydroxylase (C-P4H), a ferrous ion- and 2-oxoglutarate-dependent dioxygenase, is required to catalyse the hydroxylation of collagen proline residues to produce (2S,4S)-4-hydroxyproline. Vitamin C is the cofactor for the enzymatic activity of C-P4H.
