Ceruloplasmin (Cp), a protein that seems to be ‘Key’ regarding enzymatic functions across the body! Cp is involved in everything from digestion to brain function. It also plays a role in anti-histamine production and it has anti-microbial functions too. Ceruloplasmin is also related to our body’s Copper/Iron metabolism & ATP/energy production.
Hint hint, No Mg ATP/energy = (M$) Fatigue! ;)

Abstract
Ceruloplasmin (CP) is a mammalian blood plasma ferroxidase. More than 95% of the copper found in plasma is carried by this protein, which is a member of the multicopper oxidase family. Proteins from this group are able to oxidize substrates through the transfer of four electrons to oxygen. The essential role of CP in iron metabolism in humans is particularly evident in the case of loss-of-function mutations in the CP gene resulting in a neurodegenerative syndrome known as aceruloplasminaemia. However, the functions of CP are not limited to the oxidation of ferrous iron to ferric iron, which allows loading of the ferric iron into transferrin and prevents the deleterious reactions of Fenton chemistry. In recent years, a number of novel CP functions have been reported, and many of these functions depend on the ability of CP to form stable complexes with a number of proteins.”
