“The increase in immunoreactivity noted with Fe2+/Fe3+ or Mn2+ can be blocked with either EDTA or antioxidants (GSH and ascorbic acid), suggesting that it takes place during a peroxidative reaction of the lipids.”
“In the presence of 100 microM EDTA , 5 microM Fe(III) ions nearly completely inhibited the formation of the hydroxyl radical adduct of DMPO (DMPO-OH) as well as the formation of DMPO-OOH and, when 100 microM hydrogen peroxide was present, produced DMPO-OH exclusively.”

“ EDTA in this system … potential of ferric ion and of its iron complex thereby facilitating the transfer of one electron from NADPH to tri-valent iron (more rapidly than … a flavin moiety in the reductase, but it diminishes the concentration of free iron to be required for phospholipid peroxidation.”
“In presence of Fe3+ , HL also exhibits reversible change in emission pattern with EDTA and thus offers an interesting property of molecular ‘INHIBIT’ logic gate with Fe3+ and EDTA as chemical inputs.”
“Published experimental data on ethylenediaminetetraacetic acid (EDTA) biodegradation in the presence of ferric iron (Fe(III) ) showed that rapid biodegradation of EDTA suddenly stopped, leaving a residual of unbiodegraded EDTA that was equal to the concentration of dissolved Fe(III).”
“This analysis using CCBATCH's new sub-model for kinetically controlled complexation shows that EDTA , once it becomes complexed with Fe(III) , becomes biologically unavailable.”
