Chelate bond
WebNov 18, 2024 · A chelate is a specific kind of chemical compound that is more easily dissolved and absorbed than other types of molecules and chemical compounds. It is made up of a metal ion and a chelating agent that creates multiple soluble bonds to the ion. This chemical structure makes it easier for chelates to be absorbed in a solution. Webchelates. Each molecule or ion of a coordination compound includes a number of ligands, and, in any given substance, the ligands may be all alike, or they may be different.
