Iron in biology. Iron in hemoglobin is the source of the red coloration of vertebrate blood. Iron is an important biological element. [ 1][ 2][ 3] It is used in both the ubiquitous iron-sulfur proteins [ 1] and in vertebrates it is used in hemoglobin which is essential for blood and oxygen transport. [ 4]
Banded iron formation from the Barberton Greenstone Belt, South Africa. A typical banded iron formation consists of repeated, thin layers (a few millimeters to a few centimeters in thickness) of silver to black iron oxides, either magnetite (Fe 3 O 4) or hematite (Fe 2 O 3), alternating with bands of iron-poor chert, often red in color, of similar thickness.
Geobiology employs molecular biology, environmental microbiology, organic geochemistry, and the geologic record to investigate the evolutionary interconnectedness of life and Earth. It attempts to understand how the Earth has changed since the origin of life and what it might have been like along the way.
