31. It is used as a chelating diamine for the preparation of metal catalysts. 32. It is used widely as an acidifier, as a flavoring and chelating agent. 33. The acid has been observed to chelate metal ions such as calcium and magnesium. 34. Pellets containing iron phosphate plus chelating agents are consumed by earthworms and other invertebrates. 35. These organic acids are known as chelating agents. 36. Its chelating properties are useful in deactivating calcium and magnesium ions in hair products. 37. It is a complex of 4 Mg 2 + ions chelating six anthocyanin molecules. 38. IMAC enrichment is based on phosphate affinity for immobilized metal chelated to the resin. 39. Cobalt can also chelate lipoic acids, impairing oxidation of pyruvate or fatty acids. 40. The GLA domain binds calcium ions by chelating them between two carboxylic acid residues.
