Ferritin the Iron

Ferritin is a protein that stores iron and releases it in a controlled fashion Hence the body has a buffer against iron deficiency (if the blood has too little iron ferritin can release more) and to a lesser extent iron overload (if the blood and tissues of the body have too much iron ferritin can help to store the excess iron) Get price

what chemical reaction involved in producing iron

Rust forms when iron (Fe) reacts with oxygen (o2) to produce iron oxide (F32O3) – Redox Reaction When iron (Fe) reacts with oxygen (O2) in the air iron oxide (Fe2O3) is formed Iron oxide is a form of rust and the chemical reaction is known as an oxidation reaction Get price

Rusting of Iron

Therefore the iron atom readily gives up electrons when exposed to oxygen The chemical reaction is given by: Fe → Fe 2+ + 2e – The oxidation state of iron is further increased by the oxygen atom when water is present 4Fe 2+ + O 2 → 4Fe 3+ + 2O 2-Now the following acid-base reactions occur between the iron cations and the water molecules Get price
