锌（Ｚｉｎｃ）是人类和动物机体必需微量元素之一。随着对锌的研究不断深入，人们发现锌与生命过程密切相关，在已确认的１５种必需微量元素中，锌以功能多、作用广而被誉“生命的火花”微量元素。现已证明，锌参与体内１２０多种酶的生物合成［７］，调节３００多种酶促反应?
Zinc is one of the essential trace elements for the human and animal body. With the deepening of the research on zinc, it is found that zinc is closely related to the life process. Among the 15 essential trace elements that have been identified, zinc is widely known as the trace element of “Spark of Life” with many functions and extensive functions. It has been demonstrated that zinc participates in the biosynthesis of over 120 enzymes in the body [7] and regulates more than 300 enzymatic reactions.
