Vitamin C (Vitamin C, Ascorbic Acid), also known as L-ascorbic acid, is a water-soluble vitamin.
Vitamin C in food is absorbed by the upper part of the human small intestine. Once absorbed, it is distributed to all water-soluble structures in the body. The active pool of vitamin C metabolism in normal adults is about 1500 mg of vitamin C, and the maximum storage peak is 3000 mg of vitamin C.
Under normal circumstances, most of vitamin C is metabolized and decomposed into oxalic acid in the body or combined with sulfuric acid to form ascorbic acid-2-sulfuric acid, which is excreted in the urine; the other part can be excreted directly from the urine.
