QMB - Quantitative and medical biochemistry

The Biochemistry course offers a concise overview of the dynamic metabolic networks in the cell focusing on the general principles of enzyme kinetics, structure and control of metabolic pathways. Aspects essential for future specialists in Biotechnology are emphasized: modern biochemical techniques in the characterization of intermolecular interactions and enzyme action, in silico modelling of biochemical processes and systems. Medical orientation is implemented with discussion of the molecular basis of selected diseases with major public health impact (cardiovascular, neurodegenerative diseases) focusing on the molecular targets of therapy. Students participate in formal lectures, tutorials and computer-simulated practical lessons.
