Copper acts as a cofactor for several enzymes, including cytochrome c oxidase and superoxide dismutase, which are crucial for mitochondrial energy production and neutralizing free radicals, respectively. It also plays a role in iron metabolism by aiding in the conversion of iron to its transportable form. The exact pathways of copper's broader health effects remain under investigation.
