一、脂蛋白 脂蛋白的化学组成与分类脂蛋白(lipoprotein)由脂质分子与蛋白质通 过非共价结合而形成并存在于动物血液中,参与脂类物质转运的一类复合体。脂类一般不溶于水,但人们发现存在于血清或血浆中的脂质分子能与水溶性介质相融

一、酶的结构 1.酶的组成成分根据组成成分,酶可分为两类:单纯酶仅由蛋白质组成的酶。结合酶——除蛋白质外,还有非蛋白质成分。全酶=酶蛋白+辅因子辅因子有两种:

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

Preface Veterinary Clinical Pathology: Veterinary Laboratory medicine Include: 1 Clinical Hematology 2 Clinical biochemistry 3 Clinical cytology 4 Clinical microbiology 5 Clinical parasitology 6 Clinical toxicology

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
