铜是机体的必需微量元素,具有多方面的代谢功用,主要是作为酶的构成成分或激活剂起作用。当机体绝对或相对(zn/cu比值增高)缺铜时,因影响代谢,致使生长发育受阻,甚至引起疾病。有人报道,血浆铜水平降低是冠心病发病的危险因素,婴幼儿缺铜影响生长发育;孕妇缺铜易发生早产等。本文通过介绍铜在代谢中的作用以阐明其功用。 Copper is an essential trace element of the body, has a wide range of metabolic functions, mainly as a component or activator of enzymes play a role. When the body absolute or relative (zn / cu ratio increased) copper deficiency, due to the impact of metabolism, resulting in growth and development blocked, and even cause disease. It was reported that plasma copper levels lower risk of coronary heart disease risk factors, infants and young children lack of copper affect growth and development; pregnant women lack of copper premature birth prone. This article elucidates the role of copper in metabolism.
