Micro & Macro-éléments

On distingue ainsi selon leur concentration :

les macro-éléments (entre 30 à 1300 g pour un corps humain de 70 Kg)
les micro-éléments (entre 1 à 10 g pour un corps humain de 70 Kg)
les oligo-éléments (<1 mg/Kg)

Ils jouent un rôle de catalyseur ou de régulateur, par exemple d’activateurs enzymatiques.
