Proteins are the main functional units in the cell. In this course, a detailed overview of protein structure and function will be given with strong emphasis on the basic principles in the field. Students will be introduced to folded and intrinsically disordered proteins. Biophysical methods to study protein stability and folding will be discussed, as well as experimental approaches to determine protein structure and function. Students will be introduced to catalysis, kinetics, and the mechanisms that regulate enzyme activity. Finally, proteomic methods to studying protein networks in cells will be presented. The course will offer a solid basis in protein biochemistry. It is recommended for those interested in pursuing graduate studies or professional degrees in health or medicine.
