Product Description

Vitamin C has a structure similar to glucose and is a polyhydroxy compound. The two adjacent enol-type hydroxyl groups in the 2nd and 3rd positions of the molecule are easily dissociated to release H+, so they have acid properties. ascorbic acid. Vitamin C has strong reducibility and is easily oxidized to dehydrogenated vitamin C, but its reaction is reversible, and ascorbic acid and dehydroascorbic acid have the same physiological functions, but dehydroascorbic acid continues to oxidize to form diketone Leuconic acid, the reaction is irreversible and completely loses physiological efficacy.

Function of Vitamin C

Vitamin C is formed by antibodies and collagen, tissue repair (including some redox effects), metabolism of phenylalanine, tyrosine, folic acid, utilization of iron and carbohydrates, synthesis of fat and protein, maintenance of immune function, and hydroxy And serotonin, to maintain the integrity of blood vessels, promote the absorption of non-heme iron, etc., while vitamin C also has antioxidant, anti-free radicals, inhibit the formation of tyrosinase, thereby achieving whitening, blemish effect.
In the human body, vitamin C is a highly potent antioxidant used to reduce the oxidative stress of the ascorbate peroxidase substrate. Vitamin C is also required to participate in many important biosynthetic processes.
Since most mammals can rely on the liver to synthesize vitamin C, there is no shortage of problems; but a few animals such as humans, primates, and woodchucks cannot synthesize themselves, and must be ingested through food, drugs, and the like.
