Overview

Course Description
This course is focused on the fundamental aspects of proteins, including their chemical and physical structure, synthesis and stability, and function. In addition to these fundamentals, classical and contemporary methods used to purify and analyze proteins, and determine or predict their structure will be covered. Current topics in protein structure and proteomics will also be examined.

Learning Activities

Instruction will be a combination of lecture, guest lectures, seminar, in-class activities and student presentations.

Means of Assessment

Evaluation will be carried out in accordance with Douglas College policy. The instructor will present a written course outline with specific evaluation criteria at the beginning of the semester. Evaluation will be based on the following:

Evaluation Marks
Quizzes and/or assignments   15-25
Group project  5-15
Midterm examination 20-30
Final examination 30-40
Total   100

 

 

Learning Outcomes

After completion of this course, students will be able to:

1.  Identify the structures of the common amino acids in proteins

2.  Describe the biosynthesis of the common amino acids in proteins

3.  Describe the common elements found in primary, secondary, tertiary and quaternary structure

4.  Explain the role of molecular chaperones

5.  Explain the different methods used to identify protein structure

6.  Describe the typical Michaelis-Menten kinetics of enzymes, and also describe the effects of enzyme inhibitors

7.  Explain protein regulation, using specific examples

8.  Analyze the structure and function of membrane proteins
