本课程的任务是使学生掌握生物化学的基础理论、基本知识和基本的生化实验方法与技术，为有关后续课程的学习和继续深造奠定基础，本着既考虑生物化学自身的系统性和完整性，又顾及体现农学类专业的特点和教学工作实际的原则，本大纲共分十一章：第一章为绪论；第二至第四章为静态生化部分，重点介绍生物大分子；第五至第十章为动态生化部分，重点介绍糖类、脂类、氨基酸和核苷酸的基本代谢以及能量代谢；第十一章重点介绍信息代谢

强化学生的食品工艺学理论知识,同时使其具有必需的食品工艺操作方面的知识,掌握 一些典型食品的生产工艺,了解制定这些工艺条件的依据。 通过学习本课程,要求学生做到以下几点: 1、能较好地将食品工艺的理论知识贯通,应用于实际操作中; 2、熟悉、掌握不同食品原料的化学性质、物理性质和加工特性。学会使用相关的食品添加剂

有机酸酯可用醇和羧酸在少量无机酸催化下直接酯化制得。 当没有催化剂存在时，酯化反应很慢；当采用酸作催化剂时，就 可以大大地加快酯化反应的速度。酯化反应是一个可逆反应。为 使平衡向生成酯的方向移动，常常使反应物之一过量，或将生成 物从反应体系中及时除去，或者两者兼用

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

Overview: As you may discover, growing single crystals takes patience as well as an artful hand Crystallizations can be very sensitive to temperature and minor disturbances. Therefore, you will be encouraged to try several different temperatures using otherwise identical conditions, and to always find a quiet undisturbed location to promote crystal growth. Here are some tried and true tips to get

Working on a vacuum manifold: See LLP chapter 9.2 for an excellent discussion on working with air-sensitive reagents, including how to use a two-way manifold. De-gassing solvents: The best way to remove water and oxygen from a solvent is to distill it over an appropriate drying agent (such as sodium). This can sometimes be a lengthy (and dangerous)task. Since we

Thin Layer Chromatography (TlC) is an extremely useful technique for monitorin reactions. It is also used to determine the proper solvent system for performing separations using column chromatography. tLC uses a stationary phase, usually alumina or silica, that is highly polar(standard) or non-polar(reverse phase). The mobile phase is a solvent whose polarity you will choose. In 5.301, and in most lab
