VitaminC (English: vitamin C, also known as L- ascorbic acid) is an essential nutrient for higher primates and other few organisms. In organisms, vitamin C is an antioxidant, because it can protect the body from the threat of oxidants. The effective group of vitamin C is ascorbic acid ion, and it is well known that vitamin C deficiency can cause scurvy.
Vitamin C in food is absorbed by the upper part of human small intestine. Once absorbed, it will be distributed to all water-soluble structures in the body. There is about 1500mg vitamin C in the vitamin C metabolism pool of normal adults, and the highest storage peak is 3000mg. Under normal circumstances, most vitamin C is decomposed into oxalic acid or combined with sulfuric acid to generate ascorbic acid -2- sulfuric acid, which is excreted in urine. The other part can be excreted directly through urine.
