Ceruloplasmin metabolism and function
WebFeb 25, 2024 · Ceruloplasmin, the main copper-binding protein in blood and some other fluids, is well known for its copper-dependent enzymatic functions and as a source of copper for cells. What is generally unknown or ignored is that, at least in the case of blood plasma and serum, about half of ceruloplasmin is in the apo (copper-free) form. WebAug 28, 2024 · Ceruloplasmin is essential for maintaining the ionic state of iron, in particular, oxidizing Fe ++ to Fe +++ and preventing the formation of toxic iron products. Copper metabolism: Copper is absorbed from the gastrointestinal system in food. 1.5 to 3 mg/day of dietary copper is safe and adequate for the body.

WebCeruloplasmin helps move iron from the organs and tissues of the body into the blood. This protein prepares iron for incorporation into a molecule called transferrin, which transports the iron to red blood cells. There are two forms of ceruloplasmin. One form, serum ceruloplasmin, is made primarily in the liver. WebApr 4, 2007 · The blue coloured plasma protein ceruloplasmin binds up to 95% of circulating copper, and has several possible functions. It has been proposed to function in copper transport, oxidation of organic amines, iron (II) oxidation and the regulation of cellular iron levels, and catechols, radical scavenging and other antioxidant processes.

WebWhat is it used for? A ceruloplasmin test is most often used, along with copper testing, to help diagnose Wilson disease. Wilson disease is a rare genetic disorder that prevents the body from removing excess copper. It can cause a dangerous buildup of copper in the liver, brain, and other organs. WebDespite the need for copper for the functions of ceruloplasmin, this protein plays no essential role in the transport or metabolism of the copper. The biological role of …
WebFeb 11, 2024 · Iron accumulation is an important cause of various brain diseases. As a ferroxidase, ceruloplasmin (Cp) plays a key role in iron homeostasis and its abnormal activity leads to iron accumulation. However, the detailed biological function of Cp in brain iron homeostasis needs to be investigated. In this study, Cp knockout mice were …
