一、引言比较普遍存在于生物体内的元素大约有30种,其中金属元素17种,它们存在的普遍性如表1所示。这些金属元素与肽链组成一系列的金属蛋白。由于含金属的生物分子在生命中起着丰富多采的作用,而引起生物、化学和物理等领域的科学家的广泛兴趣。近年来已逐渐 I. INTRODUCTION There are about 30 kinds of elements commonly found in organisms, including 17 kinds of metal elements. The universality of their existence is shown in Table 1. These metal elements and the peptide chain form a series of metal proteins. As metal-containing biomolecules play a rich and diverse role in life, they have attracted a great deal of interest among scientists in the fields of biology, chemistry and physics. In recent years has gradually
