Course activities Lectures. I will present summaries of each chapter in the textbook. These presentations will include a combination of my lectures to you (from electronic PowerPoint files, available on D2L, and the chalkboard), and your questions and responses in class. The textbook mainly serves as a reference to reinforce and clarify the classroom presentations. You are strongly advised to attend class regularly, since classes will include non-electronic material (not on D2L), quizzes, and homework assignments that are due. Homework. To exercise your understanding of biochemistry, I will assign four homework exercises, which will come from my own questions as well as selected problems in the textbook. Your homework assignments will be submitted at various class periods throughout the semester. Homework assignments will provide opportunities for you to earn extra-credit points. From each assignment, only one question will be graded. You will receive half-credit (10 points) for simply doing the homework, and full-credit for correctly answering the graded question. To receive credit, homework must be submitted at the beginning of class (dates to be announced later), in hardcopy form (no electronic submissions). Quizzes. There will be four quizzes that will encourage you to keep up with studying biochemistry between the exams. They will take place at the end of the lecture (on the dates indicated), requiring approximately 15 minutes of time. Quizzes will be graded, and like homework, they will provide opportunities for you to earn extra-credit points. Therefore, the quizzes can only help improve your course grade. Their format will be a combination of shortanswer questions. No make-ups will be allowed on missed quizzes. Exams. There will be two mid-term exams during the semester, during regular class time. These exams will test you primarily on material that was covered in my lectures and homework assignments. They may also include some material from the textbook. The format of all exams will largely include questions that will ask you to recall specific facts such as definitions, names, chemical structures, and reactions. They will test your understanding of biochemistry and your ability to reason and compute solutions of biochemical problems, given specific information. During each exam, you will not be permitted to use any outside information, including your textbook, paper notes, computers, phones, etc. You will be allowed to use a calculator (non-programmable) on mid-term exams #1 and #3, and on the final exam. The mid-term exams will cover material as indicated in the course schedule (see page 2). The final exam will cover all material in the course. Note that the final exam will start at 10am on Dec 8. If you miss an exam, you will only be allowed to make it up if you provide a legitimate excuse from a physician (if you are sick or incapacitated), pre-approved university event (such as athletics), or car mechanic (if your car is wrecked). 3 3. Course grading scheme points (each) Exam 1 and Exam 2: Final Exam: points (sub-total) 300 400 600 400 points (sub-total): 1000 Extra credit 4 quizzes: 4 homework exercises: 20 20 80 80 points (grand total) 1160 You must earn: at least 900 points to make an A, at least 800 points to make a B, at least 700 points to make a C, and at least 600 points to make a D. How to earn an A in this course. Biochemistry is a challenging subject to master. It combines reasoning skills in chemistry, mathematics, and logic with the complexity of biology at the molecular level. Fundamentally, living processes do obey the laws of chemistry and physics. This is the particular power of learning biochemistry. To master biochemistry and to earn an A, you should study regularly and attentively, as in other courses. Try to read the assigned sections on the text before each lecture. Review your notes promptly after class, re-read the text, and be sure to see me if your have unresolved questions or need clarifications. You should remember biochemical structures and mechanisms, by drawing them on a blank sheet of paper repeatedly from memory. The homework assignments are designed particularly to exercise your reasoning skills. The quizzes are designed to test your knowledge of biochemistry. The exams are designed to test your cumulative comprehension of biochemistry. On the exams, you will likely see similar questions from the homework and quizzes. Strive to understand the underlying chemical and physical logic of biochemistry, and you will do very well in this course. 4. Course learning objectives This course will build up from atoms to building blocks (amino acids, nucleotides, sugars, and lipids) of biological polymers (proteins, nucleic acids, carbohydrates, and fats). Ultimately, biochemistry has to be presented in the context of cells, organs, and organisms. While it is almost impossible to remember every fact in the text and lectures, I do expect you to know important chemical structures, reactions, and biochemical pathways. I will points these out to you in lectures as the course progresses, so that you will know what to study in preparation for each exam. More importantly, you should strive to understand the chemical logic of biological molecules and reactions. Biochemistry is very much an experimental science, still under rapid development. You will hear about experimental techniques that are used to obtain some of the facts that are presented in the textbook. 1. Using the Henderson-Hasselbalch equation, determine the charge and protonation state of biomolecules in physiological solutions, and describe their behavior and function in terms of their state. 2. Master the basic principles of protein structures. You will be able to recognize and sketch all 20 amino acids, and classify them according to their properties. You will be able to recognize and define the folding of proteins in terms of their primary, secondary, tertiary, and quaternary structures. You will be able to define protein folding in terms of the rotational conformation of the polypeptide backbone and interactions of the amino acid residues. You will be introduced to a variety of experimental techniques for studying structure and function of proteins, including types of chromatography, electrophoresis, mass spectrometry, X-ray crystallography, and NMR spectroscopy. 4 3. Master the basic principles of nucleic acid structure and function. You will be able to recognize and sketch the bases, pairing, and backbone of nucleic acids. You will be able to recognize and describe the differences between DNA and RNA in both structure and function in living cells. 4. Be introduced to the flow of genetic information. You will learn about the genetic code, the biochemical machineries that transcribe DNA into RNA, and translate RNA into protein. You will be introduced to a variety of experimental techniques for sequencing genomes, cloning genes, and regulating gene expression in bacteria and eukaryotic cells. 5. Be introduced to genetic sequence analysis and evolution. You will learn about bioinformatic computations, which are used to classify life forms, identify genes, predict protein structure and function, and identify mutational differences that are correlated to human health and disease. 6. Visualize and understand how the conformational flexibility of proteins regulates their functions. You will study several case examples, including hemoglobin, myoglobin, myosin, and metabolic enzymes. 7. Analyze and quantify the kinetics of enzyme reactions. You will learn about mechanisms of enzyme inhibition and regulation. 8. Analyze catalytic mechanisms of enzymes. You will study several case examples, including trypsin, chymotrypsin, carbonic anhydrases, restriction enzymes, and ATPases. 9. Master the basic principles of the structure and function of carbohydrates and lipids. 10. Be introduced to the components and organization of cell membranes. You will learn about phospholipids, membrane proteins, ion channels, and ATPase pumps. 11. Be introduced to signal-transduction pathways. You will learn about hormone receptors, GTPase amplifiers, and cAMP second messengers. You will study a few case examples, including insulin and Ras pathways, and correlate defects in them to diabetes and cancer. 12. This course will cover a large territory of information, which will lay the groundwork for tackling many specialized areas of biological science. Therefore, you should strive to understand how biomolecules work together to carry out the myriad tasks in cells. Hopefully, you will begin to see the unifying chemical logic that underlies life in all of its great diversity. That is the most important lesson to glean from this course. 5. Other important information Research Opportunities. Undergraduate Research in Biochemistry (BIOC 4990): 1-6 credits, up to a maximum of 10. You can contribute toward a real, ongoing research project within a laboratory of the Department of Biochemistry & Molecular Biology. Responsibilities: 1 credit = minimum of 3 hours of lab work per week for an entire semester. You would normally work under supervision of a graduate student. Your project would culminate with a presentation of the results of your project to the professor and other lab members. The following points bear repeating … Syllabus Attachment.
