The Goal of this course: By studying this course, students can understanding kinetics, preparation and purification, and immobilization of enzymes. Also, knowing of applications and reactors of enzyme is another important task of students. Finally, students should master something in enzyme catalysis in organic media and some common, useful industrial enzymes

在有机化学课程学习基础上,通过本课程的学习,达到在有机合成方面能初步掌握如何 正确设计合成路线并学习几种较常规的合成方法进一步学习在近代结构分析中占有极其重 要地位的波谱理论,特别是核磁共振谱、红外光谱和紫外光谱为进一步扩大学生的知识面, 在上述基础上,对另一些近代有机理论作初步介绍,以满足学生今后在工作上对这方面知识 的需要

有机物质直接进入水体后,通过微生物的生 物化学作用而分解为简单的无机物质二氧化碳和 水,同时在分解过程中需要消耗水中的溶解氧; 在缺氧条件下,该类污染物就发生腐败分解,恶 化水质,所以称之为需氧有机污染物

Vitamins are organic chemicals required by the body in trace amounts but which cannot be synthesized by the body. The vitamins required for growth and maintenance of health differ between species; compounds regarded as vitamins for one species may be synthesized at adequate rates by other species. For example, only primates and the guinea-pig require ascorbic acid (vitamin C; section 6.4) from their diet; other species possess the enzyme gluconolactone oxidase which is necessary for the synthesis of vitamin C from D-glucose or D-galactose

Introduction: Weathering The Breakdown of Rock At the Earth's surface, rocks are exposed to the effects of weathering: the chemical alteration and mechanical breakdown of rock, when exposed to air, moisture, and organic matter. Weathering is an integral part of the rock cycle. Weathering converts rock to regolith

Preface The BIOTOL series of texts are designed to provide a self-study resource concerning the principles, practices and applications of biotechnology. This text is designed to explain how biotechnology may be applied to solve problems encountered in the production and use of organic chemicals in a wide
