酶是一种大分子的球状蛋白质,有单纯氨基酸组成的,也有含金属离子或小分子辅基的结合式蛋白质。目前已知的酶有1000种以上,但可供药用的只有50多种,而临床常用的就更少了。酶类药物已应用在消化系统疾病、炎症、血栓、烧伤、肿瘤等。在酶的应用技术上已有了新的进展,临床治疗中,应用了酶微囊、酶导管、脂酶体等新方法。并且正在研究实验有 Enzymes are globular proteins of macromolecules that consist of simple amino acids and also contain bound proteins that contain metal ions or small molecule prosthetic groups. Currently there are more than 1000 enzymes, but only for more than 50 kinds of medicinal, but less commonly used in clinical. Enzymes have been used in digestive diseases, inflammation, thrombosis, burns, tumors and more. In the application of enzyme technology has been new progress, clinical treatment, the application of enzyme microcapsules, enzyme catheters, liposomes and other new methods. And there is research experiment there
