镁是人体必需的，且需要量较大的元素，但它的重要作用还鲜为人知。现代医学认为，镁离子是细胞代谢中许多酶的活化剂，它对心肌细胞的线粒体的氧化”磷酸化具有兴奋作用，它还可以激动心肌环化腺昔辅酶，在心脏细胞能量代谢方面起着重要作用［‘j。若体内缺镁，会引起供应心脏 Magnesium is required by the body and requires a large amount of elements, but its important role is still poorly understood. In modern medicine, magnesium ions are activators of many enzymes in cell metabolism. They are excited by mitochondrial oxidative phosphorylation of cardiomyocytes. They can also stimulate the myocardial adenylate coenzyme, which plays a role in the energy metabolism of cardiac cells Important role [’j. If the body lack of magnesium, can cause the supply of the heart
