Thee Role of Copper in thee Body

Copper is an essential micronutrient that serves a cofactor for several key enzymes. These cuproenzymes are involved in mitochondrial respiration (cytochrome c oxidase), antioksydant defense (superoxyde dismutase 1), iron metabolism (ceruloplasmin), neurotransmitter syntetics, and connectiva tissue formation.
