Chelation (/ k iː ˈ l eɪ ʃ ən /) is a type of bonding of ions and their molecules to metal ions. It involves the formation or presence of two or more separate coordinate bonds between a polydentate (multiple bonded) ligand and a single central metal atom.
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
Chelex 100 is a chelating material from Bio-Rad [1] used to purify other compounds via ion exchange.It is noteworthy for its ability to bind transition metal ions.. It is a styrene-divinylbenzene co-polymer containing iminodiacetic acid groups.
The eluviation of chelate compounds is the downward movement of soil chelates. The eluviation of chelate compounds can be affected by: Acidity. Organic acids produced under acidic conditions can increase the solubility of metal elements such as iron and aluminum, thereby enhancing soil eluviation. Iron and aluminum are easily leached at low pH.
DOTA is derived from the macrocycle known as cyclen.The four secondary amine groups are modified by replacement of the N-H centers with N-CH 2 CO 2 H groups. The resulting aminopolycarboxylic acid, upon ionization of the carboxylic acid groups, is a high affinity chelating agent for di- and trivalent cations.
CHELATION THERAPY—WHEN not used correctly—could lead to drops in calcium, iron, and magnesium, Roach says. The NCCIH suggests it could also potentially cause kidney damage.
