Copper (Cu)




It is essential in all higher plants and animals. Copper is a mineral available in traceable amounts throughout the body incorporated into organic complexes, such as enzymes involved in brain function and the circulatory system. It is also extremely important for the development of the long bones, like the femur. Copper deficiency results in thin bones that fracture easily. Copper is an oxidant, yet in the body it has an antioxidant function by being a co-factor in the enzyme superoxide dismutase (S.O.D.). This enzyme protects the cells from the damage caused by free radicals and peroxides. Copper is also part of the protein, ceruloplasmin, found in the blood plasma. Ceruloplasmin regulates the level of certain hormones in the blood and is also required for the formation of red blood cells. Additionally, copper plays a part in energy production, melanin formation and fatty acid oxidation. Copper deficiency increases the risk of heart and circulatory problems, especially if there is also a selenium deficiency. Copper deficiency can also contribute to anaemia, bone diseases, nervous system disturbance and hair loss. In children, growth is inhibited and the bones may become brittle.



Nickel (Ni)



Nickel is found in highest concentrations in lung, kidney and some hormone-producing tissues.



Nickel deficiency has been linked to low blood glucose levels, abnormal bone growth, poor absorption of ferric iron, and altered metabolism of calcium, vitamin B-12 and energy nutrients.

铜(copper)




铜是人体健康不可缺少的微量营养素，对于血液、中枢神经和免疫系统，头发、皮肤和骨骼组织以及脑子和肝、心等内脏的发育和功能有重要影响。



缺铜时人体内各种血管与骨骼的脆性增加、脑组织萎缩，还可以引起白癜风及少白头等黑色素丢失症。铜在长骨,像股骨的成长中扮演极重要角色。



缺乏铜会引起瘦骨容易折断。铜虽是一个氧化剂,然而,它在体内和 抗氧化物岐化酶 (S.O.D.)则扮演抗氧的角色 。 抗氧化物岐化酶保护细胞被自由基和过氧化氢氧化。铜也是蛋白质中的一部分。铜也在能源生产、黑色素形成和氧化脂肪酸方面发挥了功用。缺乏铜会增加心脏和循环系统问题风险的,尤其是同时也缺乏硒。缺乏铜会促进贫血、骨骼疾病、神经系统紊乱和脱发。



镍 (Nickel)



镍发现高度集中在肺，肾脏和一些生产激素的组织。缺乏镍会引起低血糖水平、不正常骨骼增长,降低铁的吸收能力和改变新陈代谢钙、维生素B-12和能源营养素的能力。因此贫血病人血镍含量减少，而且铁吸收减少，镍有刺激造血功能的作用，人和动物补充镍后红细胞、血红素及白细胞增加。

New Year 2012

It is the beginning of the year and due to the workload, I am not able to write on this blog however with the beginning of the year, I will try my best to share the knowlege I know with all of you. I also do hope contribution from the readers so as to enrich this site. 新年的开始，带来无穷的生活力。我也希望在这年里我能有所贡献。去年因为工作的原因不能按时写文章，希望今年可以完成心愿。我也欢迎读者能对这网页有贡献。谢谢！
