four points are fundamental : copper is combined with essential enzymatic systems ( oxidases , transaminases ) , copper is necessary for inclusion of iron in the molecule of hemoglobin , copper has a primordial role in the metabolism of molecule of hemoglobin , copper has a primordial role in the metabolism of collagen and elastin and some vascular diseases ( aneurysms ) are closely related to its lack , finally , there is an increase of plasmatic copper during cancerous diseases , which is significant even at an early time and usually proportional to the evolution .
