Products Usage
1.Ascorbic acid, also known as vitamin C, serves various essential functions in the human body. It acts as an antioxidant, a cofactor for numerous enzymatic reactions, a coenzyme, a flour treatment agent, a food antioxidant, a plant metabolite, a skin-lightening agent, and a food color retention agent.
2.Ascorbic acid is an organic compound belonging to the group of unsaturated polyhydroxy alcohols. It is a water-soluble ketolactone with a five-membered carbon ring. It has strong reducing properties due to double bonds at the C2 and C3 carbons and four hydroxyl groups. Ascorbic acid serves as a hydrogen or electron donor, making it a cofactor in many enzymatic reactions.
3.While most mammals can produce ascorbic acid from glucose, humans lack the necessary enzyme and must obtain it from their diet. The daily requirement for ascorbic acid intake varies, with women needing around 75 mg and men around 90 mg. While citrus fruits are commonly associated with ascorbic acid, other fruits, vegetables, and meats also serve as dietary sources.
4.Ascorbic acid is a key low-molecular-weight antioxidant that regulates levels of reactive oxygen species (ROS) and enhances the effectiveness of other antioxidants. It plays a role in ROS regulation at their formation stage and donates a single reducing equivalent. It stimulates the activity of antioxidant enzymes like superoxide dismutase (SOD) and is crucial for collagen synthesis.
Package And Storage
Package:
25kg/carton drum or as your requirements.
Remark: Chemical composition and size can be optimized by the customers' requirements
Storage:
Separated from strong oxidants and strong bases.Solutions of ascorbic acid are rapidly oxidized in air and in alkaline media; the drug should be protected from air and light.
