一、铜在人体中的分布和存在状态铜是生命必需的微量元素,参与人体内许多重要的代谢过程和生理作用,一般成人体内含铜1.4～2.1mg/kg体重,幼儿含铜量是成人的三倍,因为他们的代谢过程需铜量比成人更大。人体各组织的正常代谢都需要铜,其中有的组织需铜量较大,各组织及体液的含铜量就反映了这种情况(见表1)。由表1可见,肝,脑、心脏含铜量较高;其次是胃、肠,内分泌腺、脾、肌肉;其余含铜较少。肝可能是体内铜的贮存器官。而胆囊和胆汁是过量铜排
I. Distribution and Existing State of Copper in the Human Body Copper is an essential trace element involved in many important metabolic processes and physiological functions in the human body. Generally, the adult body contains 1.4-2.1 mg / kg body weight of copper, Three times as much because their metabolic processes require more copper than adults. The normal metabolism of human tissues requires copper, some of which require a larger amount of copper, the copper content of tissues and body fluids to reflect this situation (see Table 1). Can be seen from Table 1, liver, brain, heart copper content is higher; followed by the stomach, intestine, endocrine glands, spleen, muscle; the rest contain less copper. The liver may be the body’s copper storage organ. The gallbladder and bile is excessive copper row
