Density … Under equilibrium cooling conditions, liquid iron first solidifies with a body centred cubic (bcc) crystal structure at 1538 °C which then transforms to a face centred cubic (fcc) structure at 1394 °C; finally, this fcc solid transforms again into a bcc structure at 912 °C which is stable right up to room temperature and below (Chipman, 1972). This strong interaction assures proper iron homeostasis in animal cells under iron shortage. American Mineralogist Crystal Structure Database. Is the inner core of the Earth pure iron? https://doi.org/10.1016/j.str.2005.09.009. Woodhouse J. H.. Shearer P. M. Woodhouse J. H.. Morelli A. Users can perform simple and advanced searches based on annotations relating to sequence, structure and function. (2014). Nov 15, 2002. [Fe(H 2O) 6](ClO 4) 3 3H 2O Acta Cryst. Describe the crystal structure of iron, which crystallizes with two equivalent metal atoms in a cubic unit cell. A., Oxford University Press is a department of the University of Oxford.

The inner core, most remote part of our planet, is composed of solid iron. The pattern was taken by Pei Yan. Colin M. Sayers, The crystal structure of iron in the Earth's inner core, Geophysical Journal International, Volume 103, Issue 1, October 1990, Pages 285–286, https://doi.org/10.1111/j.1365-246X.1990.tb01770.x. Crystal Structure of Human Iron Regulatory Protein 1 as Cytosolic Aconitase. Using our proposed structure prediction algorithm coupled with first-principles calculations, we performed crystal structure prediction on a series of iron-rich iron carbide phases (FexCy, 1 ≤ y ≤ x ≤ 7, 0 < y/x ≤ 1) with not more than 32 total number of atoms per cell at T = 0 K and P = 0 GPa. Thus, BCC structure of a-iron is more loosely packed than that of FCC γ-iron, and that is why density of FCC γ-iron is 8.14 g/cm3 at 20°C and 7.87 g/cm3 for α-iron. Here, we report the crystal structure of human IRP1 in its aconitase form. Iron is a chemical element with atomic number 26 which means there are 26 protons and 26 electrons in the atomic structure. In this paper the X‐ray structure and magnetic properties of iron(II) acetate – starting material for the synthesis of a wide range of iron complexes – are presented. This WebElements periodic table page contains crystal structures for the element iron (2013); Lindstrand (1936). Iron is a metal in the first transition series. Toy K. M. Giardini D. The specific features of human IRP1 allow us to propose a tentative model of an IRP1-IRE complex that agrees with a range of previously obtained data. Thus the crystal structure of iron is of prime importance for understanding the nature of solid inner core. Li X.-D. Iron regulatory proteins (IRPs) control the translation of proteins involved in iron uptake, storage and utilization by binding to specific noncoding sequences of the corresponding mRNAs known as iron-responsive elements (IREs). The dimeric structure adopts a globular fold, resembling a vase of 37 Å in height. Pallavi Arod, S. A.
