Chronic toxicity by copper is rare. [1] The suggested safe level of copper in drinking water for humans varies depending on the source, but tends to be pegged at 1.3 mg/L. [2] So low is the toxicity of copper that copper(II) sulfate is a routine reagent in undergraduate chemistry laboratories. [3]
In the case of copper the adult UL is set at 10 mg/day. [4] Copper gluconate is sold as a dietary supplement to provide copper. The typical dose is 2.0 mg copper per day. This is one-fifth what the IOM considers a safe upper limit. Long-term intake at amounts higher than the UL may cause liver damage. [4]
Cu 2+-SOD + O 2 − → Cu +-SOD + O 2 (reduction of copper; oxidation of superoxide) Cu +-SOD + O 2 − + 2H + → Cu 2+-SOD + H 2 O 2 (oxidation of copper; reduction of superoxide) The protein hemocyanin is the oxygen carrier in most mollusks and some arthropods such as the horseshoe crab (Limulus polyphemus).

For many people, coffee is the drink of choice first thing in the morning. The beverage made from what adults think of as magical wake-up beans gives the boost of energy many need to get out of bed.
Normal absorption and distribution of copper. Cu = copper, CP = ceruloplasmin, green = ATP7B carrying copper. Copper is an essential trace element that is vital to the health of all living things (plants, animals and microorganisms). In humans, copper is essential to the proper functioning of organs and metabolic processes.
Copper is a chemical element with the symbol Cu (from Latin: cuprum) and the atomic number of 29. It is easily recognisable, due to its distinct red-orange color.Copper also has a range of different organic and inorganic salts, having varying oxidation states ranging from (0,I) to (III).
