虽着科学的进展,一门新的边缘学科生物无机化学正在突起,作为人体内必需微量元素已成为主要研究对象。人体的必需微量元素目前已由1974WHO公布的9种元素发展为14种。它们是人体的某些酶、激素、维生素等不可缺少的成份,并促进其活性。对机体代谢、人的生长发育、免疫机能都有极重要的生物学意义。即使这些元素只占人体重量的万分之五,但它们确是人类生命活动所必需的,它们在营养学中比维生素更为重要。在健康人体中可借助于体内的某些蛋白质、激素使体内必需微量元素处于一定的浓度范围。当人体处于不利的
Despite the progress of science, a new edge of biological bio-chemistry is emerging, as essential trace elements in the human body has become the main research object. Essential trace elements of the human body has now been developed by the 1974WHO nine kinds of elements to 14 species. They are the body’s certain enzymes, hormones, vitamins and other indispensable ingredients, and promote their activity. On the body metabolism, human growth and development, immune function has a very important biological significance. Even though these elements make up only five ten-thousandths of the human body weight, they are indeed essential to human life activities and are more important in nutrition than vitamins. In healthy people can help some of the body’s proteins, hormones so that the necessary trace elements in the body at a certain concentration range. When the human body is at a disadvantage
