The pharmacophore is E300 ascorbic acid ions. In vivo, E300 is an antioxidant, because 50-81-7 oxidants to protect the body from the threat, E300-50-81-7 is also a coenzyme. As the VCs own chemical structure and biological activity, E300-50-81-7 can be as sour agent, reducing agent, antioxidant, bleaching agent and stabilizer used in cosmetics, food, medicine in.

Uptake of E300-50-81-7 need
North American recommended daily dietary reference intake intake of at least 90 mg E300-50-81-7, but do not exceed 2000 mg daily. But other species need not produce E300 20 times the amount recommended intake to 80 times. The best scientists are debating the frequency of intake of E300 (each dose and take the time interval). But in the normal adult, even if the E300 intake, as long as a balanced diet, was able to prevent acute scurvy, and pregnancy, smoking, stress, or who need to intake of E300-50-81-7 more . Ingestion of high doses (tens of milligrams) may result in diarrhea, but as long as the reduced intake is not immediately harmful to humans. Support drug substitution program (not taking medication and E300) the person is declared the lowest dose sufficient to diarrhea E300 is the real demand. End-stage cancer or serious illness of influenza E300 intake up to 200 grams of diarrhea without any conditions. Symptoms increase, the body will increase the E300-50-81-7 intake to combat viruses and other highly stressful crises.
