Introduction

Vitamin C is a water-soluble vitamin, chemically named L - (+) - threitol 2,3,4,5,6-pentahydroxy-2-hexene-4-lactone, also known as L-ascorbic acid, with a molecular formula of C6H8O6 and a molecular weight of 176.12.

Vitamin C is usually a sheet-like, sometimes needle shaped monoclinic crystal, odorless, sour in taste, easily soluble in water, and has strong reducibility. Participating in the complex metabolic processes of the body can promote growth and enhance resistance to diseases. It can be used as a nutritional supplement, antioxidant, and wheat flour improver. However, excessive supplementation of vitamin C is not beneficial to health, but rather harmful, so it needs to be used reasonably. Vitamin C is used as an analytical reagent in the laboratory, such as a reducing agent, masking agent, etc.

Application

Synthetic medicinal vitamin C is exactly the same as natural vitamin C. The product can promote folic acid to tetrahydrofolic acid, is conducive to nucleic acid synthesis, promote the production of red blood cells. It can also reduce trivalent iron ions to bivalent iron ions, which is easy to be absorbed by the body and is also beneficial to the generation of cells. Vitamin C is involved in the production of collagen in the body. It has the function of neutralizing toxin and promoting antibody production
