Iron, as a topic, encompasses its roles and behavior across diverse scientific domains, including its coordination chemistry, redox properties, and biological functions. Central to many metalloproteins, iron cycles between Fe²⁺ and Fe³⁺ states, enabling electron transfer, oxygen transport, and catalysis in systems such as hemoglobin, cytochromes, and iron–sulfur clusters. In materials science, iron’s allotropic transformations, magnetic ordering, and alloy formation underlie the properties of steels and other ferrous materials. In geoscience, iron participates in redox-sensitive mineral formation and biogeochemical cycling, influencing atmospheric composition, nutrient availability, and environmental redox gradients across terrestrial and marine systems.
Plants fix 258 billion tons of CO2 in their chloroplasts through photosynthesis every year. For these cell organelles to work properly, they require certain minerals—particularly ions of the metals iron (Fe), manganese (Mn), ...
