英文名称 | Ethylenediaminetetraacetic acid dipotassium salt dihydrate |
生化机理 | Ethylenediaminetetraacetic acid (EDTA) is an anticoagulant, majorly used in preventing clotting of blood. EDTA may trigger aggregation of platelets resulting in pseudothrombocytopenia. EDTA-tetracycline therapy decreases coronary artery calcium levels in atherosclerosis. Calcium disodium EDTA administration is effective in slowing down the progression of chronic kidney disease. It also enhances the antimicrobial functionality of lysozyme and improves shelf life of cheese. |
