As an essential micronutrient, copper is required for a wide range of physiological processes in virtually all cell types. Because the accumulation of intracellular copper can induce oxidative stress and perturbing cellular function, copper homeostasis is tightly regulated. Recent studies identified a nov...
CuZ 4 Tetrahedron N2O reductase μS2 −[4Cu(NδHis)7O(?)] a Copper centers are often described as having distorted versions of these geometries The type I (T1Cu) group of copper proteins is probably the most studied and characterized. Most members of this group are electron transfer prot...
1 Among the energy conversion technologies, water electrolysis is considered as a promising method to produce hydrogen, which is a clean energy carrier with a high energy density of approximately 142 MJ kg−1.2,3 Water electrolysis consists of two half-reactions, namely the oxygen evolution ...
Cells tightly regulate their copper homeostasis through a network of copper-dependent proteins, which maintain the intracellular copper content within specific ranges [6]. Maintaining copper homeostasis is essential to avoid the adverse effects of both copper deficiency and copper overload [6]. An imba...
it contains the most effective proteins and other components that exhibited a wide range of biological properties4,5. Both bovine LF and LP are considered the most effective constituents of whey proteins, besides other proteins such as α-lactalbumin (α-LA) and immunoglobulins. LF is one of th...
此处是谓语动词,依据前文are可知是一般现在时,主语paste和color之间是被动关系,所以用被动语态,主语是单数,所以用is colored,故填is colored。(4)考查冠词。句意:容器通常在相对较低的温度下,约800摄氏度下烧制。此处是泛指,所以用不定冠词,relatively是辅音音素开头,所以用a,故填a。(5)...
They are trimeric proteins in which the monomer is a 140–400 amino acid polypeptide with three transmembrane regions (Dumay et al., 2006). These proteins have methionine-rich regions frequently present in the N-terminal extracytosolic region and a conserved MM motif in the second transmembrane ...

In addition, a higher probability of bridge CO adsorption on metallic Co was also observed over the CuCoMn catalyst, which was beneficial for the formation of CHx intermediates. It is concluded that a synergistic effect between Cu+ and Co species, promoted by the presence of manganese species,...
The copper bis-(N-cyclohexyldiazeniumdioxy) system (Cu-HDO, CX) consists of the biocides Cu-HDO, additional uncomplexed copper(II), and boron. The Cu-HDO portion exhibits good stability, but the borate component can quickly leach and the uncomplexed copper is also subject to some leaching....
