Copper is inorganic element ,that needed for human health,and even its toxic,but with small amounts are needed,
opper, an essential mineral, is naturally present in some foods and is available as a dietary supplement. It is a cofactor for several enzymes (known as “cuproenzymes”) involved in energy production, iron metabolism, neuropeptide activation, connective tissue synthesis, and neurotransmitter synthesis [1-3]. One abundant cuproenzyme is ceruloplasmin (CP), which plays a role in iron metabolism and carries more than 95% of the total copper in healthy human plasma [4]. Copper is also involved in many physiologic processes, such as angiogenesis; neurohormone homeostasis; and regulation of gene expression, brain development, pigmentation, and immune system functioning [1]. In addition, defense against oxidative damage depends mainly on the copper-containing superoxide dismutases [5,6].
A wide variety of plant and animal foods contain copper, and human health affect health.So how copper is affecting health.
