This module delves into the structure-function relationship of proteins and the forces influencing the regulatory, structural, protective, and transport roles of proteins. In addition, the principles and application of biochemical techniques as well as the expression, separation, identification and purification of proteins will be explored. The module integrates biochemistry and molecular cell biology using bioinformatics and analytical instruments as tools to facilitate this large-scale, complex study of proteins. The practical component of the module, which allows students to apply the concepts covered in the theory component, introduces students to materials, equipment and laboratory techniques that are frequently used in protein studies such as protein extraction, SDS PAGE, Western blot, and columns chromatography.
