ادامه مطلبIntroduction. Copper (Cu) is an essential micronutrient that is important to plants, animals, and humans as a constituent of several enzymes and as a redox catalyst in a variety of metabolic pathways (Citation Devez et al. 2005).The deficiency of Cu may result in reduction of biological function and potentially death.
