  1. Form a chelate with

  1. chelate: relating to or characterized by chelation
  2. form a chelate, in chemistry
  3. (chelate) a heterocyclic compound having a metal ion attached by coordinate bonds to at least two nonmetal ions
  4. (chelate) having or resembling chelae or claws
  5. (chelation) (medicine) the process of removing a heavy metal from the bloodstream by means of a chelate as in treating lead or mercury poisoning
  6. (chelation) the process of forming a ring by forming one or more hydrogen bonds
  7. Chelation is the formation or presence of two or more separate bindings between a polydentate (multiple bonded) ligand and a single central atom. Usually these ligands are organic compounds, and are called chelants, chelators, chelating agents, or sequestering agents.
  8. bound with one or more chelates
  9. (chelation) the formation of a polydentate chelate compound from a metal salt; the use of this process to remove metal ions from solution, especially to counter poisoning by heavy metals
  10. (Chelate) combining nutrients in an atomic ring that is easy for plants to absorb.
  11. (chelate) To form a complex chemical compound in which an ion, usually metallic, is bound into a stable ring structure
  12. (Chelate) A chemical compound whose molecules contain metal (iron) atoms.
  13. (Chelate) a coordination complex containing rings formed by polydentate ligands
  14. (CHELATE) (Pronounced KEY-late) — also called sequester — It is the process of preventing metals in the water from combining with other components in water to form colored precipitates that stain the pool walls and bottom or produce colored water.
  15. (Chelate) A compound formed when a metallic ion is bound to an organic molecule; used to improve availability of minerals.     Chelation is a process in which a substance, typically a mineral, binds with a protein, a mechanism which is believed to enhance the body's absorption ability rate.
  16. (Chelate) A corrdination compound in which a heterocyclic ring is formed by a metal bound to two atoms of the associated ligands.
  17. (Chelate) A molecule that contains more than one binding site and frequently binds to another molecule through more than one binding site at the same time.
  18. (Chelate) In mites (Acari), mandiblelike chelicerae.
  19. (Chelate) The word translated from the Greek word “chel”, means crab’s claw. It refers to the claw like manner in which a metal (usually iron) is bound in the molecule. Chelation loosely binds metal ions in an inner circle. They allow it  to be moved freely within a cell and plant. ...
  20. (Chelate) a complex organic molecule that surrounds certain trace elements, such as iron, and keeps them dissolved in a solution.
  21. (chelate) Combine reversibly, usually with high affinity, with a metal ion such as iron, calcium, or magnesium.
  22. (chelate) Having a chela; the propodus and dactylus forming a pincerlike structure wherein the latter articulates submedially on the former to produce a "moveable and fixed finger" arrangement. (True chelae are extremely rare in isopods.)
  23. (chelate) Noun: Complex organic molecule that can combine with cations and does not ionize. Chelates can supply micronutrients to plants at slow, steady rates. Usually used to supply iron to plant cells.
  24. (Chelates) Chelated minerals are minerals that are attached to other molecules such as simple carbohydrates or proteins to improve their bioavailability (increasing their affinity for uptake across the digestive tract wall). ...
  25. (Chelates) Many companies use the term chelated minerals in their labeling. This does not mean amino acid chelated. There are other chelators: gluconates are from corn, citrates are made from corn steep liquor, molasses, hydrolyzed corn starch with certain strains of the mold Aspergillus niger. ...
