|Biochemistry is the field of studies on molecules and chemical reactions of living things. The basic principles of biochemistry are common to all organisms such as bacteria, plants, and humans. Therefore, the findings of any research that is carried out on particular organism may be applied to almost all other species. The biochemistry course analyzes mainly the structure and function of biomolecules: physical-chemical properties and metabolisms of nucleic acids, proteins, carbohydrates and lipids; the mechanism of enzyme kinetics, coenzymes, etc. The course will introduce the close relationship between the chemical and physical properties of biomolecules and their functions. The regulation and integration of these critical metabolic processes with each other will be emphasized. Students will comprehend the importance of chemical changes on the function of biological systems. Moreover, they will be able to use this knowledge to apply and combine with the topics of other related courses in the field. This course is taken concurrently with a laboratory course.
|The cognitive, affective and behavioral objectives of this course are following:
• Introduction to the energetics of life: the first and second law of thermodynamics to predict the direction of chemical reactions that occur in biological systems.
• Explaining the intermolecular interactions: mechanism of covalent and non-covalent interactions, charge-charge interactions, hydrogen bonds, Van der Waals forces and hydrophobic interactions.
• Describing ionization of water: acid/base chemistry as it applies to biological molecules.
• Illustrating structure and function: basic molecular properties of the 4 classes of biological molecules (proteins, carbohydrates, lipids and nucleic acids) and the subunits from which they are formed and explaining how the structure of biological molecules dictates function and how changes in structure direct biochemical reactions.
• Describing properties and mechanisms of enzymes: the catalytic functions of enzymes, and performing enzyme kinetics calculations.
• Defining organic reaction mechanisms: the network of chemical reactions that make up central metabolism.
• Providing a general background in the biochemistry field: analyzing scientific literature pertaining to subject matter in biochemistry.
• Giving an outline of scientific mysteries: applying knowledge and concepts to novel problems.
