Iron is a necessary trace element used by all known living organisms. In mammals and other animals, hemoglobin is the iron-containing metalloprotein that carries oxygen in red blood cells. Good sources of dietary iron include meat, beans, and leafy vegetables; however, excessive amounts of iron...
An iron silicide thermoelectric conversion element wherein a part of one of components of the silicide is substituted by oxygen atom to form either Si-O bond or Fe-O bond in a matrix of the compound to provide either p-type conductivity or n-type conductivity as desired....
Iron is a key trace element for virtually all organisms. It functions as an essential co-factor in central cellular processes such as respiration, metabolite biosynthesis, DNA synthesis and repair, ribosome biogenesis, and oxygen transport in vertebrates. Although iron is highly abundant, its bioavail...
Iron (Fe) is an element. Iron (Fe) is a metallic element that is typically silvery-gray in color, with a lustrous shine in its pure form. It is solid at room temperature and has a metallic odor when heated. Iron is one of the most abundant elements in the Earth's crust and is kn...

Iron is an essential element for all organisms, and iron-requiring proteins play a crucial role in a variety of cellular processes, such as energy metabolism, DNA synthesis, DNA repair, cell cycle progression, epigenetic regulation, and response to hypoxia18,19,20. At the biological level, ...
Iron is an essential element that plays a vital role in oxygen transport and many other metabolic processes. Despite the relatively small amount of iron required per day, nutritional iron deficiencies are prevalent throughout the world. A major cause is the fact that most forms of food and inor...
Iron is atrace elementintegral to multiple metabolic processes, includingDNA synthesis[157]and the metabolic demand for iron is greater in neoplastic than in normal cells[254]. Indeed, intracellulariron depletionis known to result in anti-tumour activity, prompting the development ofchelating agentstha...
