General Biochemistry I

At the end of the lectures, students should be able to: 1. explain the structure of different macromolecules in biological system; 2. identify types of chemical reactions involving these macromolecules; 3. explain the various methods of isolation of these macromolecules; 4. estimate the effects of acids and alkalis on the macromolecules; 5. describe purification of macromolecules; and 6. quantify the various macromolecules.
