Chemicals that combine with metal ions and remove them from their sphere of action, also called sequestrants. They are used in food manufacture to remove traces of metal ions which might otherwise cause foods to deteriorate and clinically to reduce absorption of a mineral, or to increase its excretion; e.g. citrates, tartrates, phosphates, and EDTA

What agents are considered slow effect agents?
Cyanide
Why were the prohibition agents called the untouchables?
Those were honest agents who would not take bribes.
What blood agents?
Prothombin
Are bacteriocidal agents sterilants?
No
What is the role of export agents?
Export agents locate and develop markets abroad for products that are manufactured in their home countries.
Name some chelating agents?
One natural chelating agent is tannic acid.
How is chelation responsible for weathering?
chelation is the break down of certain minerals in rock by chelating agents. chelating agents are organic acids released by the decomposition of organic matter in soil.
How can you purge your body from toxins?
chelating agents work for toxic metals
Is chelating agent negatively charged?
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 .
What were chelation agents first used for?
Chelating agents, most commonly diamine tetraacetic acid (EDTA), were originally designed for industrial applications in the early 1900s.
What are the main chelating agents used in selenium chelation?
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.
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+
What is ferrous ion chelating?
Chelating is the coordination (binding) of a metal ion by an organic molecule through more than one coordinating bond (for example EDTA binds metals through six bonds in an octahedral pattern). Chelating usually allows a higher solubility of the metal in aqueous solution. Ferrous chelation is the binding of the Iron (II) ion (as opposed to the Iron (III) or ferric ion). Many chelating agents (like EDTA) have different affinities for metals in different oxidation states.
What is the most common agent used in chelation therapy?
Chelating agents, most commonly diamine tetraacetic acid (EDTA), were originally designed for industrial applications in the early 1900s.
What factors affect enzyme stability?
temperature (most of them denature above 45* C ), pH (best range is 4.5 - 8.1), inhibitors (ions used for fractionation, chelating agents)
What is edtmpa?
EDTMPA is short for Ethylenediaminetetramethylene phosphonic acid, which is a chemical compound commonly used as a sequestrant and chelating agent in various industrial and water treatment applications. It is effective in binding and removing metal ions to prevent scale formation in water systems.
How is heavy metal poisoning treated in alternative medicine?
Alternative practitioners often rely on the same chelating agents used by standard doctors to treat heavy metal poisoning, but also use natural supplements and additional techniques
