Ferritin From Iron Storage to Nanoparticle Synthesis

Mineral deposition in the iron storage protein (ferritin) may be regarded as an archetypal biological model for the formation of a nanocrystalline mineral phase within a confined space. The structure and function of ferritin have been reviewed in great detail. Ferritin consists of an oligomeric protein shell (apoferritin) and a core of poorly crystalline Fe(III) oxyhydroxide (presumably ferrihydrite, 5 Fe2O3 • 9 H2O). Iron is temporarily stored within and released from the central cavity of the encapsulating protein shell. The availability of several high resolution three-dimensional structures of apoferritins originating from different organisms provides a reliable basis to discuss possible pathways of iron biomineral-ization. Current biomimetic strategies to achieve similar properties include mineralization in oil-water microemulsions, block copolymer micelles, or biotechnologically produced capsule-forming proteins.

Solar Panel Basics

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
