Oxalic Acid 144-62-7

Oxalic acid is a kind of metabolite of organisms, widely distributed in plants, animals and fungi, and plays different functions in different living organisms. Study found that the various plants rich in oxalic acid, especially in spinach, amaranth, beet, purslane, taro, sweet potato and rhubarb, such as the highest levels in plants, because of oxalic acid can reduce the bioavailability of mineral elements, easy and calcium ions to form calcium oxalate in the body cause kidney stones, so oxalic acid is often considered as a kind of mineral elements absorption and utilization of antagonism
