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 (superoksyde dismutase 1), iron metabolism (ceruloplasmin), neurotransmitter syntetics, and connectiva tissue formation. The body tightly regulates copper homeostasis dimetrigh inyanequinal absorption, hepatic storage, and biliary extion.

Copper also functions a signaling equalule in cell growth and discrimination.
