Iron responsive secondary structure

Outline the role of RNA secondary structure in the regulation of iron metabolism in animals. Describe the roles of transferrin, transferrin receptor, ferritin, the iron-response element, and IRE-binding protein. Relate the IRE-binding protein to aconitase and iron sensing. 

Low-energy electron-diffraction (LEED) techniques are used to detect adsorbed films, including those responsible for passivity. Surface analytical techniques that can be used to study films on metals include Auger electron spectroscopy (AES), X-ray photoelectron spectroscopy (XPS), secondary ion mass spectrometry (SIMS), and others [18,19]. Using these advanced techniques, evidence has been developed to show that the passive film formed on iron in borate solution is an anhydrous, crystalline spinel with a Y-Fc203/Fe304-like structure [19].
