A chelating agent contains multiple sites capable of binding to a metal ion, forming a stable complex. These sites often have lone pairs of electrons that can coordinate with the metal ion. Chelating agents typically form a ring structure around the metal ion, enhancing the stability of the complex.
Not necessarily. Chelating agents can be neutral too. For example en (ethylenediamine), etc. The only condition for a ligand to be called a chelating agent is that it should coordinate with the metal in a manner so as to form a ring .
Tertrasodium EDTA is a chelating and preservative agent.
Chelating agents in yeast cells help to bind and remove heavy metal ions from the environment. This can help to detoxify the cell, prevent metal toxicity, and protect cellular components from damage. Chelating agents can also be a defense mechanism against environmental stresses caused by heavy metal exposure.
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+
No, EDTA (ethylenediaminetetraacetic acid) is a chelating agent, not an enzyme. EDTA binds metal ions and is commonly used in laboratories to prevent metal ion contamination in reactions or to chelate metal ions in solutions.

chlorine is used as disinfactant and as a chelating agent
A dehydrating agent is usually an acid which brings about loss of water molecule when used on an hydrated compound. A chelating agent is usually an electron donour (ligand) which forms a complex by coordinating with a metal using two or more donor groups of a single ligand.
A chelating agent (also known as a complexing or sequestering agent) is a compound that forms stable complexes with metal ions. Control of metal ion activity in aqueous systems is the main use of chelating properties so precipitation of sparingly soluble salts such as those of of calcium and magnesium with inorganic anions, fatty acids and anionic surfactants can be avoided. Typical applications are scale control and water softening.
A ligand is an ion or molecule that binds to a central metal atom to form a coordination complex. The bonding usually involves the formal donation of one or more of the ligand's electron pairs. A chelating agent is a type of ligand.
An aminodiphosphine is a compound containing an amino group and two phosphine groups, especially such a compound used as a chelating agent.
Sleneium is the main chelating agent in the selenium chelation process it is present in the human body normally in small quantities and can be used to extract mercury from the body helping to treat mercury poisoning.
EDTMPA is white crystal powder at room temperature, with melting point 215-217℃, hard to be dissolved in water, the solubility is less that 5% at room temperature, easy dissolved in ammonia. EDTMPA has strong metal ion chelating capacity, whose chelating constant with cuprum ion is larger than that of EDTA. EDTMPA has high capacity for chelating metal ions. The complex constant with Cu is the largest in all chelating agents including EDTA. EDTMPA is a kind of high-pure grade reagent and innocuous, it can be used as detergent in semiconductor chip to prepare integrated circuit, as carrying agent for radioelement in medical industry, and as agent for inspection and therapy. The chelating capacity of EDTMPA largely exceed that of EDTA and DTPA, and can replace EDTA for chelating agent at almost any situation. Information Source From http://www.thwater.net/01-EDTMPA.htm

Chelating agents can also be a defense mechanism against environmental stresses caused by heavy metal exposure.
Some common chelating agents include ethylenediaminetetraacetic acid (EDTA), citric acid, diethylene triamine pentaacetic acid (DTPA), and hydroxyethyl ethylenediamine triacetic acid (HEDTA). These compounds have multiple binding sites that can form stable complexes with metal ions.
