Product Description of Ascorbic Acid CAS#50-81-7
Vitamin C, also known as L-ascorbic acid, is an essential nutrient for humans and certain other organisms. While most species can synthesize ascorbic acid through metabolism, humans cannot and must obtain it from external sources. Deficiency of vitamin C is well known to cause scurvy.
Pharmacologically, vitamin C functions as the ascorbate ion. In the body, it acts as a powerful antioxidant, helping protect cells from oxidative damage, and also serves as a coenzyme in various important metabolic reactions.

Product Applications of Ascorbic Acid CAS#50-81-7
Vitamin C plays an important role in human metabolism, promoting growth and enhancing resistance to disease. It is widely used as a food nutrient fortifier, with regulated application levels in candies, cereals, infant foods, canned fruits, beverages, and fruit purées. It is also valued for its strong reducing ability and antioxidant properties.
As an antioxidant, it is applied in fermented flour products and beer to improve product stability. In addition, it serves as an effective nutritional enhancer in various food formulations.
Synthetic vitamin C is chemically identical to natural vitamin C. In the body, it supports folic acid conversion, promotes nucleic acid and red blood cell formation, improves iron absorption, and participates in collagen synthesis. It also helps neutralize toxins, enhance antibody production, and strengthen detoxification functions.
In pharmaceutical use, vitamin C is mainly applied for the prevention and treatment of scurvy and for conditions such as anemia, gum disease, dental problems, and growth disorders caused by deficiency.
