3 lecture hours/week; 1 tutorial hour/week
Course description: This modular survey course will introduce students to modern topics in chemical biology with an emphasis on applications of organic chemical principles to biological research and biotechnology. The course is divided into three modules as follow:
The topics to be covered in the lectures will include an overview of the major classes of biomolecules (nucleic acids, proteins, carbohydrates) from the perspective of chemical biology. Examples of chemical probes used in imaging, chemical genetics, and emerging methods for manipulating the levels and activities of biomolecules will be described. Examples of major experimental advances accomplished using these methods and tools will be noted with an emphasis will be placed on current and classic papers in the primary literature as well as critical review of recent research papers. Though not required, owing to the interdisciplinary nature of the subject matter of this course, students will benefit from an introductory-level understanding of biochemistry as well as cell and molecular biology.

COURSE-LEVEL EDUCATIONAL GOALS:
Expected outcomes: Students will learn to read and critically analyze scientific papers in chemical biology. Students will learn the current state of the field of chemical biology. Students will learn how other fields in chemistry impact and enable chemical biology research. Students will learn how chemical biology is an enabling field for academic and industrial research.
Literature discussions and presentations: The reading of scientific literature is an essential skill for scientists in all sectors; government, private, and academic. One aim of this course will be to improve skill at reading the literature through practice and discussion. Classes will therefore involve discussion of assigned literature during tutorials. Prior to class discussion students will prepare a concise write-up on the assigned questions. During class discussion we will briefly analyze the assigned paper and evaluate connections to the lecture material. Each student will also present a current paper from the chemical biology literature with approval from the instructor, summarizing the work, defining the key advances, and outlining the signficance of the work for the wider field.
- Discussion Write-ups and Participation 35%
- Short Problem Sets 15%
- Presentation 20%
- Module Quizzes 30%
Online Exam Invigilation: Students completing exams remotely must comply with the online invigilation procedures implemented by the course instructor.
MATERIALS + SUPPLIES:
Technology Requirements: Students are required to have a desktop or laptop computer, high-speed internet access, and a webcam and microphone (built-in or external) to participate in online courses.
Lectures will be based largely on the primary literature and the following text by Profs. Van Vranken & Weiss at UC Irvine:
- Van Vranken, D. L. & Weiss, G. A. Introduction to Bioorganic Chemistry and Chemical Biology
Additional reading is recommended for students with limited background in introductory biochemistry, biological chemistry, and molecular and cell biology. The following books are either available on-line at the PubMed bookshelf or have been requested to be on reserve in the Bennett library. Some can be found on the PubMed bookshelf (online).
- Alberts, B. A., et al. Molecular Biology of the Cell (4th edition and onward).
- D. Voet and J.G. Voet, Biochemistry, (3rd edition and onward).
- Blackburn, G.M & Gait, M.J. Nucleic Acids in Chemistry and Biology (2006 edition)
- Varki, A., et al. Essentials of Glycobiology, (2009) (available on-line)
Graduate Studies Notes:
Important dates and deadlines for graduate students are found here: http://www.sfu.ca/dean-gradstudies/current/important_dates/guidelines.html. The deadline to drop a course with a 100% refund is the end of week 2. The deadline to drop with no notation on your transcript is the end of week 3.
ACADEMIC INTEGRITY: YOUR WORK, YOUR SUCCESS
SFU’s Academic Integrity web site http://www.sfu.ca/students/academicintegrity.html is filled with information on what is meant by academic dishonesty, where you can find resources to help with your studies and the consequences of cheating. Check out the site for more information and videos that help explain the issues in plain English.
Each student is responsible for his or her conduct as it affects the University community. Academic dishonesty, in whatever form, is ultimately destructive of the values of the University. Furthermore, it is unfair and discouraging to the majority of students who pursue their studies honestly. Scholarly integrity is required of all members of the University. http://www.sfu.ca/policies/gazette/student/s10-01.html
TEACHING AT SFU IN SPRING 2021
Teaching at SFU in spring 2021 will be conducted primarily through remote methods. There will be in-person course components in a few exceptional cases where this is fundamental to the educational goals of the course. Such course components will be clearly identified at registration, as will course components that will be “live” (synchronous) vs. at your own pace (asynchronous). Enrollment acknowledges that remote study may entail different modes of learning, interaction with your instructor, and ways of getting feedback on your work than may be the case for in-person classes. To ensure you can access all course materials, we recommend you have access to a computer with a microphone and camera, and the internet. In some cases your instructor may use Zoom or other means requiring a camera and microphone to invigilate exams. If proctoring software will be used, this will be confirmed in the first week of class.Students with hidden or visible disabilities who believe they may need class or exam accommodations, including in the current context of remote learning, are encouraged to register with the SFU Centre for Accessible Learning (email@example.com or 778-782-3112).
