代谢
铜主要通过胃肠道吸收,但也可以通过吸入和皮肤吸收。它通过基底外侧膜,可能是通过调节铜转运蛋白,并与血清白蛋白结合被运输到肝脏和肾脏。肝脏是铜稳态的关键器官。在肝脏和其他组织中,铜以与金属硫蛋白、氨基酸以及与依赖铜的酶结合的形式储存,然后分配通过胆汁排泄或并入细胞内和细胞外蛋白中。铜通过血浆中与血清白蛋白、铜蓝蛋白或低分子量复合物结合的方式被运输到外周组织。铜可能诱导金属硫蛋白和铜蓝蛋白的产生。膜结合的铜转运腺苷三磷酸酶(Cu-ATPase)将铜离子输送到细胞内和细胞外。体内生理正常水平的铜通过改变铜的吸收速率和数量、分布区域以及排泄来保持恒定。(L277, L279)
Copper is mainly absorbed through the gastrointestinal tract, but it can also be inhalated and absorbed dermally. It passes through the basolateral membrane, possibly via regulatory copper transporters, and is transported to the liver and kidney bound to serum albumin. The liver is the critical organ for copper homoeostasis. In the liver and other tissues, copper is stored bound to metallothionein, amino acids, and in association with copper-dependent enzymes, then partitioned for excretion through the bile or incorporation into intra- and extracellular proteins. The transport of copper to the peripheral tissues is accomplished through the plasma attached to serum albumin, ceruloplasmin or low-molecular-weight complexes. Copper may induce the production of metallothionein and ceruloplasmin. The membrane-bound copper transporting adenosine triphosphatase (Cu-ATPase) transports copper ions into and out of cells. Physiologically normal levels of copper in the body are held constant by alterations in the rate and amount of copper absorption, compartmental distribution, and excretion. (L277, L279)

  • 毒性总结
过量的铜被储存在肝细胞溶酶体中,在那里它与金属硫蛋白结合。当溶酶体饱和,铜在细胞核中积累,导致核损伤时,铜的肝脏毒性被认为会发生。这种损伤可能是由于氧化损伤,包括脂质过氧化。铜抑制了诸如葡萄糖-6-磷酸1-脱氢酶、谷胱甘肽还原酶和对氧磷酶等含有巯基团的酶,这些酶保护细胞免受自由氧自由基的侵害。它还影响基因表达,并且是诸如细胞色素C氧化酶和赖氨氧化酶等氧化酶的辅因子。此外,由铜引起的氧化应激被认为会激活酸性鞘磷脂酶,导致神经酰胺的产生,这是一种凋亡信号,同时也会引起溶血性贫血。铜诱导的呕吐是由于迷走神经的刺激所致。
Excess copper is sequestered within hepatocyte lysosomes, where it is complexed with metallothionein. Copper hepatotoxicity is believed to occur when the lysosomes become saturated and copper accumulates in the nucleus, causing nuclear damage. This damage is possibly a result of oxidative damage, including lipid peroxidation. Copper inhibits the sulfhydryl group enzymes such as glucose-6-phosphate 1-dehydrogenase, glutathione reductase, and paraoxonases, which protect the cell from free oxygen radicals. It also influences gene expression and is a co-factor for oxidative enzymes such as cytochrome C oxidase and lysyl oxidase. In addition, the oxidative stress induced by copper is thought to activate acid sphingomyelinase, which lead to the production of ceramide, an apoptotic signal, as well as cause hemolytic anemia. Copper-induced emesis results from stimulation of the vagus nerve. (L277, T49, A174, L280)

  • 健康影响
人们每天必须吸收少量铜,因为铜对健康至关重要。然而,高水平的铜可能有害。极高的铜剂量可能对肝脏和肾脏造成损害,甚至导致死亡。铜可能引起敏感人群的过敏反应。
People must absorb small amounts of copper every day because copper is essential for good health, however, high levels of copper can be harmful. Very-high doses of copper can cause damage to your liver and kidneys, and can even cause death. Copper may induce allergic responses in sensitive individuals. (L278, L279)

    4-aminostyrene at 100% conversion of 4-nitrostyrene in an aqueous solvent under visible light irradiation. Compared with other reported catalysts, our presented catalyst shows more superior hydrogenation selectivity and stability as well as lower material cost. This high efficiency could be originated from the nanocatalyst's ability to synergistically control surface hydrogen species released from ammonia
    结构多样的硝基芳烃的化学选择性加氢是一个具有挑战性的过程,通常需要贵金属催化剂并在有机溶剂中进行。在此,开发了一种结合碳点和铜纳米颗粒的方便且稳定的杂化纳米催化剂,作为该转化的理想选择。所制备的纳米催化剂在可见光辐射下在水性溶剂中4-硝基苯乙烯在100%转化率下实现了4-氨基苯乙烯形成的99%以上的选择性。与其他报道的催化剂相比,我们提出的催化剂显示出更优异的氢化选择性和稳定性以及更低的材料成本。这种高效率可能源于纳米催化剂 协同控制由氨硼烷释放的表面氢物种和由可见光辐照产生的高能“热”电子进行选择性还原反应的能力。与其他已报道的催化剂相比,我们提出的纳米催化剂更适合通过引入太阳能来实现节能化学过程。
