A chelate is a chemical compound composed of a metal ion and a chelating agent. A chelating agent is a substance whose molecules can form several bonds to a single metal ion. In other words, a chelating agent is a multidentate ligand. An example of a simple chelating agent is ethylenediamine.ethylenediamine. A single molecule of ethylenediamine can form two bonds to a transition-metal ion such as nickel(II), Ni 2+ .n other words, a chelating agent is a multidentate ligand.

Shares & Saves. Save. Magnesium oxide and magnesium chelate are very similar, as far as what they are used for. Magnesium is a very important mineral for our bodies, and though we can get sufficient magnesium through proper diet, many do not eat well and need extra magnesium.he difference between the two medications is that chelated magnesium is bonded to nitrogen to make sure that it does not interact with other compounds, explains nutrasanus.com.
