Iron Absorption

Ceruloplasmin, a copper-containing enzyme, oxidizes ferrous iron to ferric iron, which is essential for iron transport via transferrin and cellular iron uptake. This process ensures adequate iron availability for oxygen transport and other vital bodily functions.

Copper-containing enzymes, specifically ceruloplasmin, play a vital role in iron metabolism. Ceruloplasmin facilitates the oxidation of ferrous iron (Fe2+) into ferric iron (Fe3+). This oxidation is crucial for the transport of iron in the bloodstream via transferrin, a protein responsible for carrying iron. The conversion also enables efficient iron uptake by cells, ensuring that the body can utilize iron for essential functions such as oxygen transport and enzyme production.
