The article focuses on iron-fortified foods which are so commonplace on U.S. grocery shelves, and have been since the 1940s, that few Americans realize iron deficiency is one of the most prevalent forms of malnutrition, affecting more than one-fifth of the world population, or 1.4 billion ...
Despite its essential role as a redox co-factor, the ease with which iron gains and loses electrons makes it potentially dangerous in the cellular environment9,10. Free iron reacts with H2O2, produced by aerobic respiration, via the Fenton reaction to form highly reactive hydroxyl and hydroperoxy...
Iron plays a certain role in mythology and has found various usage as a metaphor and in folklore. The Greek poet Hesiod's Works and Days (lines 109–201) lists different ages of man named after metals like gold, silver, bronze and iron to account for successive ages of humanity.[110] ...

Iron plays a crucial role in the high-nutrient, low-chlorophyll Southern Ocean regions, promoting phytoplankton growth and enhancing atmospheric carbon sequestration. In this area, iron-rich Antarctic krill (Euphausia superba) and baleen whale species, which are among their main predators, play a lar...

Iron plays an important role in many biological processes but it has low solubility under physiological condition. Many microorganisms have been shown to be able to circumvent this nutritional limitation by forming direct contacts with iron-containing proteins through ATP-binding cassette (ABC) ...
chain to produce ATP [6,7]. In this process, ferrous iron (Fe2+) and ferric iron (Fe3+) serve as an electron donor and acceptor, respectively. In effect, iron plays an essential role in maintaining adequate stores of ATP during oxidative phosphorylation in the mitochondrial inner membrane ...
