Product Description

Vitamin C is a polyhydroxy compound with the chemical formula 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 to release H+, so it has the nature of an acid, also known as L-ascorbic acid. Vitamin C has a strong reducing property and is easily oxidized to dehydrovitamin C, but the reaction is reversible, and ascorbic acid and dehydroascorbic acid have the same physiological function. However, if dehydroascorbic acid is further hydrolyzed to form diketogulonic acid, the reaction will be irreversible and the physiological efficacy will be completely lost.

 

Application

1. Vitamin C is for the formation of antibodies and collagen, tissue repair (including certain redox effects), metabolism of phenylalanine, tyrosine, and folic acid, utilization of iron and carbohydrates, synthesis of fat and protein, maintenance of immune function, hydroxyl Antioxidant 5-hydroxytryptamine is necessary to maintain the integrity of blood vessels and promote the absorption of non-heme iron. At the same time, vitamin C also has anti-oxidation, anti-free radicals, and inhibits the formation of tyrosinase, so as to achieve the effect of whitening and lightening spots.

2. In the human body, vitamin C is a high-efficiency antioxidant used to reduce the oxidative stress of ascorbate peroxidase sch. There are many important biosynthetic processes that also require vitamin C to participate.

3. Since most mammals can synthesize vitamin C through the liver, there is no problem of deficiency; however, a few animals such as humans, primates, and groundhogs cannot synthesize vitamin C by themselves and must be ingested through food and drugs.
