The cornerstone of the treatment of Wilson’s disease is a reduction of copper levels in vivo using the orallyadministered chelating agents D-penicillamine and trientine dihydrochloride. Patients with side-effects from receiving multiple blood transfusions for the amelioration of inherited anaemias are also successfully treated with chelating agents. Blood transfusion elevates these patients’ ir...

Absorption of iron by plants can be increased by adding a chelating azent to a soil (2, 7, 24). Jacobson (9) found that 5 or 10 ppm of iron supplied as FeEDTA in solution cultures provided adequate iron to the plant at high pH. Other workers (7, 11, 12, 19, 20, 23, 24, 25) have confirmed these observations. Plant responses to chelate applications have been shown to differ between plant species ...

Several studies have been made on the bacteriostatic and fungicidal properties of oxine (8-hydroxyquinoline) and other chelating agents, and it has been suggested that they might act, in part at least, by depriving cells of essential trace metals (Albert, 1951; Martell & Calvin, 1952). In an attempt to determine the trace element requirements of mammalian spermatozoa, White (1955) investigated ...

ABSTRACT: Oxidation might be regarded as one of the most important reaction in oils and fats. Prooxidants namely iron and copper intensify and catalyze the oxidation while the chelating agents might retard or delay this process. Citric acid, phosphoric acid, some of phenolic compounds and phospholipids are considered as the compounds that chelate the prooxidant metals and through this mechanism...

Aminopolycarboxylate chelating agents are under scrutiny due to their influence on metal availability and mobility and in particular due to their persistence in the environment. In this review chelate adsorption, metal-mobilization, metalexchange, mineral dissolution, reactive transport, photodegradation, and chemical degradation are all shown to be substantially affected by the chelated metal ...
