  2. Siderophore - Wikipedia

    en.wikipedia.org/wiki/Siderophore

    The iron(III) complex is then reduced to iron(II) and the iron is transferred to nicotianamine, which although very similar to the phytosiderophores is selective for iron(II) and is not secreted by the roots. [27] Nicotianamine translocates iron in phloem to all plant parts.

  3. Chelation therapy - Wikipedia

    en.wikipedia.org/wiki/Chelation_therapy

    Chelation therapy is a medical procedure that involves the administration of chelating agents to remove heavy metals from the body. [1] Chelation therapy has a long history of use in clinical toxicology [2] and remains in use for some very specific medical treatments, although it is administered under very careful medical supervision due to various inherent risks, including the mobilization of ...

  4. Chelation - Wikipedia

    en.wikipedia.org/wiki/Chelation

    For example, species of Pseudomonas are known to secrete pyochelin and pyoverdine that bind iron. Enterobactin , produced by E. coli , is the strongest chelating agent known. The marine mussels use metal chelation, especially Fe 3+ chelation with the Dopa residues in mussel foot protein-1 to improve the strength of the threads that they use to ...

  5. Ferric EDTA - Wikipedia

    en.wikipedia.org/wiki/Ferric_edta

    Iron chelate is commonly used for agricultural purposes to treat chlorosis, a condition in which leaves produce insufficient chlorophyll. Iron and ligand are absorbed separately by the plant roots whereby the highly stable ferric chelate is first reduced to the less stable ferrous chelate. [ 6 ]

  6. EDDHA - Wikipedia

    en.wikipedia.org/wiki/EDDHA

    EDDHA or ethylenediamine-N,N ′-bis(2-hydroxyphenylacetic acid) is a chelating agent.Like EDTA, it binds metal ions as a hexadentate ligand, using two amines, two phenolate centers, and two carboxylates as the six binding sites.

  7. Chelating resin - Wikipedia

    en.wikipedia.org/wiki/Chelating_resin

    Chelating resins are a class of ion-exchange resins.They are almost always used to bind cations, and utilize chelating agents covalently attached to a polymer matrix. Chelating resins have the same bead form and polymer matrix as usual ion excha

  8. Ferrichrome - Wikipedia

    en.wikipedia.org/wiki/Ferrichrome

    The reduction strategy helps in making the iron more aqueous soluble, and allows the iron to become more bioavailable in order for uptake to occur. This is because the Fe 2+ product is not able to mineralize like the Fe 3+, as it does not bind significantly to the chelate ligand that is designed to bind Fe 3+.

  9. Pentetic acid - Wikipedia

    en.wikipedia.org/wiki/Pentetic_acid

    DTPA under the form of iron(II) chelate (Fe-DTPA, 10 – 11 wt. %) is also used as aquarium plants fertilizer. The more soluble form of iron, Fe(II), is a micronutrient needed by aquatic plants. By binding to Fe 2+ ions DTPA prevents their precipitation as Fe(OH) 3, or Fe 2 O 3 · n H 2 O poorly soluble oxy-hydroxides after their oxidation by ...
