有机化学(organic chemistry)是研究有机化合物的来源、制备、结构、性能、应用以 及有关理论和方法学的科学,是化学学科的一个分支,它的研究对象是有机化合物。 什么是有机化合物呢?早期化学家将所有物质按其来源分为两类,人们把从生物体 (植物或动物)中获得的物质定义为有机化合物,无机化合物则被认为是从非生物或矿 物中得到的

he major classes of organic compounds common to living systems are lipids, pro- teins, nucleic acids, and carbohydrates. Carbohydrates are very familiar to us- we call many of them\sugars.\ They make up a substantial portion of the food we eat and provide most of the energy that keeps the human engine running. Carbohy- drates are structural components of the walls of plant cells and the wood of trees. Genetic

This handout describes standard extraction and washing protocols that can be applied to virtually any crude reaction mixture. Aqueous washings are done to remove water soluble impurities from organic products since normally the compound that you desire will be dissolved in Reference

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
