锌作为人体必须的微量元素,参与各种人体正常的生理活动及细胞信号转导过程。锌能够保护心肌细胞,但是锌参与心肌细胞线粒体保护作用的机制尚未明确。本文就锌可能参与的心肌线粒体保护作用机制综述如下。1心肌细胞内的锌稳态锌是地球上含量居于第24位的一种过渡金属元素,作为人体必须的微量元素,参与人体正常的生理活动及体内多种酶的代谢,被认为是蛋白质以及部分蛋白酶类的一个重要组成部分[1],其中锌离子 Zinc as a human body must trace elements involved in a variety of human normal physiological activity and cell signal transduction process. Zinc protects cardiomyocytes, but the mechanism by which zinc participates in cardiomyocyte mitochondrial protection remains unclear. In this paper, zinc may be involved in myocardial mitochondrial protective mechanisms are summarized below. 1 Zinc steady-state zinc in myocardial cells is a transition metal element in the 24th position on the earth. As a necessary trace element of the human body, it participates in normal physiological activities of the body and metabolism of many kinds of enzymes in the body and is considered as protein and An important part of some proteases is zinc ion
