Details
Vitamin C, also known as L-ascorbic acid CAS 50-81-7, is one of the essential vitamins. In the body, vitamin C is an antioxidant because it can protect the body from the threat of oxidants. Vitamin C is also a coenzyme.
Vitamin C is easily soluble in water, slightly soluble in ethanol, and insoluble in ether, chloroform, benzene, petroleum ether, oils, and fats. The aqueous solution shows an acidic reaction. It can be quickly oxidized into dehydroascorbic acid in the air, which has a citric acid-like sour taste. It is a strong reducing agent and gradually turns into light yellow to varying degrees after long storage. Vitamin C exists in various fresh vegetables and fruits and is natural and safe. This product plays an important role in biological oxidation and reduction and cell respiration, is beneficial to nucleic acid synthesis, and promotes the formation of red blood cells. It can also reduce Fe3+ to Fe2+, which is easy to be absorbed by the human body and is also beneficial to cell formation.
