Iron and activated oxygen species in biology: The basic chemistry
Abstract
This paper briefly presents a critical review concerning the chemical reactions involved when superoxide or hydrogen peroxide meet iron complexes. The data commented on are required for a correct interpretation of the chemical processes which play a paramount role in the biological activation of dioxygen and arise in normal metabolism as well as in pathological processes.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
