Chelate


Definition:

  • (a.) Same as Cheliferous.

Example Sentences:

  • (2) These membrane perturbation effects not observed with bleomycin-iron in the presence of a hydroxyl radical scavenger, dimethyl thiourea, or a chelating agent, desferrioxamine, were correlated with the ability of the complex to generate highly reactive oxygen species.
  • (3) Symptoms, particularly colicky abdominal pain, improved during the period of chelation therapy.
