WebJun 3, 2013 · Depending on the specific type, a ligand will vary in its natural ability to “hold” (chemical bond between atoms) a mineral in this chelate “ring” structure. Some ligands create weak chelate structures that break apart in the digestive process, resulting in the mineral’s release and thus reverting back to an inorganic form.
WebThe chelate effect increases with the number of chelate rings formed. This explains why EDTA is a very good chelating agent, as it can form up to six coordinating bonds to the metal centre. In general, the chelate effect can be explained by using a thermodynamic approach, which considers the equilibrium constants for the reaction. WebLigands are ions or neutral molecules that bond to a central metal atom or ion. Ligands act as Lewis bases (electron pair donors), and the central atom acts as a Lewis acid (electron pair acceptor). Ligands have at least one donor atom with an electron pair used to form covalent bonds with the central atom. The term ligand come from the latin ...
