锌(Zn)、铜(Cu)与心血管疾病的关系近年一直为人们所关注,动物实验和临床及流行病学研究均证明Zn、Cu代谢与心血管疾病及其危险因素如高血压病、高血脂症的发生、发展有密切关系。1 Zn、Cu的吸收、分布及排泄1.1 Zn 体重70kg成人体内含锌1.4～2.3g,成人摄入Zn后,大部分在小肠吸收,正常人对Zn的吸收率波动在40％～80％之间,血液Zn75％～80％存在于红细胞内,构成某些酶的成分;12％～22％在血浆
The relationship between zinc (Zn), copper (Cu) and cardiovascular diseases has been attracting attention in recent years. Animal experiments and clinical and epidemiological studies have proved that Zn, Cu metabolism and cardiovascular disease and its risk factors such as hypertension, Hyperlipidemia, the development is closely related. 1 Zn, Cu absorption, distribution and excretion 1.1 Zn body weight 70kg Adult body contains 1.4 ~ 2.3g of zinc, adult intake of Zn, the majority of absorption in the small intestine, the normal absorption rate of Zn fluctuations in 40% to 80% Between the blood of 75% ~ 80% Zn exists in the red blood cells, constitute the composition of some enzymes; 12% ~ 22% in plasma
