electrical resistivity 1.71 microhm-cm at 25°C; Poisson's ratio 0.33; melts at 1,083°C; vaporizes at 2,567°C; insoluble in water; dissolves in nitric acid and hot sulfuric acid; slightly soluble in hydrochloric acid; also soluble in ammonium hydroxide, ammonium carbonate and potassium cya...
produced along with l-citrulline from l-arginine in a reaction catalyzed by endothelial nitric oxide synthase (eNOS) [44], and it can relax blood vessels, and promote the differentiation, proliferation, and migration of endothelial cells by activating NO synthetase and the MAPK signaling pathway [...
3e). NADH and copper were found in mitochondria of aMDMs at an estimated substrate:catalyst ratio of 2:1, which is even more favourable for this reaction to take place than the 20:1 ratio used in the cell-free system (Extended Data Fig. 6g). Macrophage activation was accompanied by ...

Several studies reported that the properties of CuO nanoparticles, i.e., size, shape, and stability, are strongly determined by reaction conditions such as type of precursor and its concentration, extract and its concentration, temperature, and pH. The multi-component nature of crude extract ...
It has recently been shown that protons, in addition to being a substrate in this reaction, are involved in controlling the rate of electron transfer (ET) between the type-1 Cu (T1Cu) centre and the catalytic type-2 Cu (T2Cu) centre of the enzyme5,6,7,8,9. In common with many ...
However, there is one important hindrance, as both SOD and SOD-like Cu-complexes can cleave cellular DNA by reacting with hydrogen peroxide and generating hydroxyl radicals by Fenton-type reaction (Sang and Yang2005; Han et al.2007; Seng et al.2009; Ghosh et al.2010; Ibrahim et al.2011)...
The reaction that dominates the thermodynamic equilibrium is the one-electron oxidation of copper by solvated protons from the auto-ionization of water; Cu(cr) + H+ ⇄ Cu+(aq) + ½ H2(aq). Several additional reactions take part in the equilibrium and the detailed equilibrium ...
