when all donor atoms of a polydenate ligand get coordinated with the same metal ion ,a comlex compound is formed which contains one or more rings in its structure and hence is called a chelate.
Example:metal chelates are more stable metal complexes.

Chelates are chemical compounds in which a central metal ion is bonded to a ligand through multiple coordination bonds. The ligand typically forms a ring structure that encloses the metal ion. An example of a chelate is the ethylenediaminetetraacetic acid (EDTA) complex, which chelates with metal ions such as calcium or iron to form stable complexes that are used in various applications, such as in medicine or industrial processes.

How can cheating agents act as antioxidants?
A cheating agent has a crab-claw-like ligand which coordinates to the metal ion. This decreases the concentration of free transition metals in solution so there is less chance of oxidation. An example of a chelating agent is the rosemaric acid.Chelating agents (such as EDTA) chelates the divalent metal ions such as Mg2+ or Zn2+

Why do minerals need chelates?
To my understanding, minerals don't need chelates, we need chelated forms of minerals to better be able to use them. Chelated minerals are a special form of minerals that are found in living things. If the minerals aren't chelated, living things are unable to utilize them.

Why does copper turn your wrist green?
Copper, when in contact with the skin, forms chelates with human sweat(sometimes seen as green deposits) and is thus absorbed through skin.""Copper chelates are more effective and less toxic than drugs being usedto treat arthritis.
