What is it?
Copper is essential in all higher plants and animals. It is the third most abundant
trace mineral in the human body. It is carried mostly in the bloodstream on a plasma
protein called ceruloplasmin. When this mineral is first absorbed in the gut it is transported
to the liver bound to albumin. This mineral is found in a variety of enzymes, including the
centers of cytochrome c oxidase, the Cu-Zn containing enzyme superoxide dismutase, and is
the central metal in the oxygen carrying pigment hemocyanin. The blood of the horseshoe
crab, Limulus polyphemus uses copper rather than iron for oxygen transport. It is believed
that zinc and copper compete for absorption in the digestive tract so that a diet that is
excessive in one of these minerals may result in a deficiency in the other.
