一引言催化作用,一方面和现代化学工业有着密切的联系,绝大部分的有机和无机化学工业过程都是借助于催化剂来实现的;另一方面,它又和生命现象有着密切的关系,在生物体中进行的化学过程,如呼吸、消化、蛋白质合成、光合作用,绝大部分都是借助于生物催化剂——酶来实现的。把生物催化剂和现有的工业催化剂作一番比较,我们就可 An introduction The catalytic role, on the one hand, and the modern chemical industry are closely linked, most of the organic and inorganic chemical industry processes are achieved by means of the catalyst; the other hand, it has a close relationship with the phenomenon of life in The chemical processes in living organisms, such as breathing, digestion, protein synthesis, and photosynthesis, are mostly done with the aid of biocatalysts - enzymes. We can compare biocatalysts to existing commercial catalysts
