Copper

The essential trace mineral copper forms a vital component of several enzyme systems in the human body. These enzymes are active in biochemical processes such as cellular energy generation, the formation of links in collagen molecules, and in the formation and synthesis of melanin – skin pigment, and elastin – a skin protein. Copper is also used as an important structural element in the formation of the myelin sheath, which covers the nerve fibers and aids in the rapid transmission of nerve impulses. Many important oxidation reduction reactions in the body are catalyzed by copper; these include the formation of water from the free hydrogen and oxygen present in the cells. The catalytic action of copper reduces the impact of this reaction; this biochemical reaction could be very explosive if the copperwere not present. The sense of taste generated in the human tongue is also influenced by the presence of copper.
