Copper is an essential trace element. However, excess copper can lead to oxidation of biomolecules and cell damage and copper levels must be carefully controlled. While copper homeostasis has been studied extensively at the cellular level, short-term body copper fluxes are poorly understood. Here, ...

Although copper (Cu) is recognized as an essential trace element, uncertainties remain regarding Cu reference values for humans, as illustrated by discrepancies between recommendations issued by different national authorities. This review examines human studies published since 1990 on relationships between Cu...
Copper is an essential trace element critical for normal human metabolism. Copper deficiency can occur with inadequate copper intake, but excess copper intake may cause toxicity to human. Copper and its alloys are pres- ent in numerous articles of everyday use, such as coinage, tools, jewelry,...
An element such as Cr is caused to dissolve sufficiently in a base-material metal (Cu) in a solid solution state at a high temperature and a material in a supersaturated condition is obtained by performing quenching. After that, a strain is applied to this material and this material is subj...
Copper (Cu) is a transition element, belonging to Group 11 (formerly Group IA) of the Periodic Table. It is an important non-ferrous metal and a micronutrient with two distinct functions - to serve as a plant nutrient by being an activator or by being a part of certain enzymes like tyro...
Copper is an essential trace element in living organisms where it functions primarily as either an enzyme cofactor or free form as a catalyst for the generation of radicals (Gaggelli et al., 2006). Disturbance of copper homeostasis is associated with a number of human diseases such as Wilson...
Cu is an essential element in virtually all living organisms, and numerous studies have shown that Cu serves as a cofactor for a variety of key metabolic enzymes that drive a broad range of physiological processes.3,4 Thus, the systemic Cu levels must be maintained within a narrow range to ...
