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… WebMetal acetylacetonates are coordination complexes derived from the acetylacetonate anion (CH 3 COCHCOCH − 3) and metal ions, usually transition metals.The bidentate ligand acetylacetonate is often abbreviated acac.
