Which mineral is absorbed through the intestine and transported with ceruloplasmin in the blood?

The mineral that is absorbed through the intestine and transported with ceruloplasmin in the blood is copper. Ceruloplasmin is a protein that binds copper and facilitates its transport in the bloodstream. This is particularly important because copper plays a crucial role in various physiological processes, including iron metabolism, the functioning of the nervous system, and the immune response.

Copper is absorbed primarily in the small intestine and is incorporated into ceruloplasmin in the liver before being released into circulation. This mechanism is vital for ensuring that sufficient copper is available for utilization by body tissues while also helping to regulate its levels to prevent toxicity. In contrast, iodine, sodium, and calcium have different absorption and transport mechanisms that do not involve ceruloplasmin, making copper the correct and most relevant choice in this context.
