Chelate example

In the 1960s, scientists developed the concept of chelating a metal ion prior to feeding the element to the animal. They believed that this would create a neutral compound, protecting the mineral from being complexed with insoluble salts within the stomach, which would render the metal unavailable for absorption. Amino acids, being effective metal binders, were chosen as the prospective ligands, and research was conducted on the metal–amino acid combinations. The r… WebHard chelants, for example EDTA (ethylenediamine tetra acetic acid) and NTA (Nitrilo triacetic acid), form very stable complexes with a 1:1 stoichiometry. That is to say that one EDTA molecule reacts with a single metal ion. ... form less stable complexes and function by preventing crystal growth rather than by true chelation. Both calcium and ...
