1.1 The Definition of Metabolism The highly integrated network of chemical transformations. Degradation (decreasing order, thus energy releasing) to provide energy, catabolism; Synthesis (increasing order, thus energy consuming) to provide building materials, anabolism

he next several chapters deal with the chemistry of various oxygen-containing functional groups. The interplay of these important classes of compounds-alco- hols, ethers, aldehydes, ketones, carboxylic acids, and derivatives of carboxylic acids-is fundamental to organic chemistry and biochemistry

1. Enzymes were among the first biological macromolecules to be studied chemically 1.1 Much of the early history of biochemistry is the history of enzyme research. 1.1.1 Biological catalysts were first recognized in studying animal food digestion and sugar fermentation with yeast (brewing and wine making)

(一)酶反应速度与底物浓度的关系曲线 对于简单的酶反应,当酶浓度和其他条件恒定时:

一、酶与活化能 酶的催化机理 碰撞、有效碰撞、活化分子、 活化能:活化分子所有的最低能量(Ea)与 分子的平均能量(EA)之差。分子由常态转 变为活化状态所需要的能量称为活化能

一、酶的概念 在本章节中把酶所催化的反应称作酶促反应 ,发生化学反应前的物质称底物(substrate), 而反应后生成的物质称产物(product)

一、基因组与基因组学的发展 二、基因的商品价值 三、基因组的特点

一、物理性质 1、形态DNA为白色纤维状固体;RNA为白色粉末状固体? 2、溶解性微溶于水,不溶于乙醇、乙醚和氯仿等一般的有机溶剂;DNA在溶液中粘度大,RNA粘度小
