Vitamin C is the most common water-soluble vitamin. It is mainly involved in the formation of antibody collagen in the body, the redox effect of tissue repair, fat and protein synthesis, and maintaining certain functions of the immune system. The main clinical use of vitamin C is related to scurvy caused by vitamin C deficiency. Of course, it can also be used as an adjuvant for various acute and chronic infectious diseases and purpura.

Description

1.Basic Vitamin C Administration

100 vitamin c powder herbal cosmetic grade the ordinary ascorbic acid japan (1)

Vitamin C is a polyhydroxy compound with the chemical formula C6H8O6. Its structure is similar to glucose. The two adjacent enol hydroxyl groups at positions 2 and 3 in the molecule easily dissociate and release H+, so it has the property of an acid, also known as L-ascorbic acid. Vitamin C is highly reducible and is easily oxidized to dehydrovitamin C, but its reaction is reversible, and ascorbic acid and dehydroascorbic acid have the same physiological function. However, with further hydrolysis of dehydroascorbic acid to form diketogulic acid, the reaction will be irreversible and the physiological effect will be completely lost. Vitamin C is white crystals or crystalline powder, odorless, sour, gradually turning yellow after a long time. Easily soluble in water, acidic, slightly soluble in ethanol, insoluble in chloroform or ether.
