chelates, plural;
  1. (of an appendage) Bearing chelae

Verb
  1. Form a chelate with

Noun
  1. A compound containing a ligand (typically organic) bonded to a central metal atom at two or more points

  1. relating to or characterized by chelation
  2. form a chelate, in chemistry
  3. a heterocyclic compound having a metal ion attached by coordinate bonds to at least two nonmetal ions
  4. having or resembling chelae or claws
  5. 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.
  6. (chelated) bound with one or more chelates
  7. (Chelated) The word chelate by definition means to combine with a metal (mineral). It is the bonding between a mineral and an organic molecule. ...
  8. (Chelated) the attachment of an organic or carbon-containing chemical compound to amineral. Chelating agents are often used to increase the absorption of minerals in thebody. Amino acids are very commonly used as chelating agents.
  9. (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). ...
  10. (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. ...
  11. (Chelating) A deep cleansing process which strips the hair lightly before a chemical service. Also known as clarifying.
  12. (Chelating) contain two or more atoms that tend to bind to a single metal atom, example - acetylacetonate (acac); abbreviation usually k^2.
  13. To form a complex chemical compound in which an ion, usually metallic, is bound into a stable ring structure.
  14. (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. 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.)
  16. claw-like or pincer-like; bearing chela or claws
  17. Combine reversibly, usually with high affinity, with a metal ion such as iron, calcium, or magnesium.
  18. a complex organic molecule that surrounds certain trace elements, such as iron, and keeps them dissolved in a solution.
  19. 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.
  20. 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.
  21. A corrdination compound in which a heterocyclic ring is formed by a metal bound to two atoms of the associated ligands.
  22. A complex formed by polydentate ligands (ligands that can bind in more than one place)
  23. A chemical compound whose molecules contain metal (iron) atoms.
  24. 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.
  25. combining nutrients in an atomic ring that is easy for plants to absorb.
