The pharmacodynamic group of vitamin C is ascorbic acid ion. In the organism, vitamin C is an antioxidant, because it can protect the body from the threat of oxidants, and vitamin C is also a coenzyme.

Description

Ascorbic Acid occurs as white or slightly yellow crystals or as powder. It melts at about 190°. It gradually darkens on exposure to light, is reasonably stable in air when dry, but rapidly deteriorates in solution in the presence of air.

 

Application

1) Promote the biosynthesis of collagen.

2) Promote the metabolism of tyrosine and tryptophan in amino acids and prolong the life of the body.

3) Improve the utilization of iron, calcium and folic acid.

4) Improve the metabolism of obesity and lipids, especially plasma, and prevent cardiovascular disease.

5) Promote the growth of teeth and bones and prevent gum bleeding.

6) Enhance the body's anti-stress ability and immunity to the external environment.
