CUSA1031 The Chemistry and Chemical Analysis of Biomolecules 生物分子的化學與分析


Biomolecules are loosely defined as molecules found in biological system. In the biological system, carbohydrate, protein, lipid, nucleic acid and enzyme are key biomolecules. This course covers the chemical structures of these biomolecules and their roles in biological systems. Besides, we will talk about some interesting topics that you encounter very often in daily life. For example, how do artificial sweeteners differ from table sugar? Why do artificial sweeteners have low or even zero calorie contents? Can we unboil an egg? What causes aging? Is there any method to reverse the aging process? Finally, we will talk about the basic principles of chemical analysis for various biomolecules in foods. This course comprises of both lectures and experimental sessions.
