Elective course in MSc Chemistry and MSc life Science and Technology
BSc Chemistry or BSc Life Science and Technology
Metal ions such as iron, zinc, calcium, or copper, are ubiquitous in nature. They play a major role in biology, for example for the transmission of action potential along axons, for the transport and control of oxygen-based species, or for the appearance of diseases such as Alzheimer’s disease or diabetis.
The course is aimed both at Chemistry and Life Science and Technology MSc students. It describes first the binding of metal ions to biomolecules, how different metal ions differentiate from each other, and how different biomolecules and proteins bind to different metal ions. The second part of the course describes two families of proteins: those based on zinc ions, and those involved in the production, transport, and control of dioxygen. The specific role of the metal in these different proteins is discussed. A third part of the course studies how metals are absorbed by living cells and organisms, and transported to where they are needed. Then, the role of metal imbalance in disease is discussed, as well as heavy metal pollution. Finally, the last part of the course is dedicated to inorganic drugs and the use of artificial metal-based compounds for medicine, looking at both imaging and therapy.
The students following this course will be trained to:
Be able to extract the good information from the text and figures of a scientific article and answer the question asked
Be able to sum up in proper English a range of scientific articles on a single topic
Understand the HSAB theory and how biological ligands bind to different metal ions
Understand how UV-vis, vibrational, fluorescence, NMR, and CD spectrometry, can be used for analyzing the interaction between metal ions and biomolecules
Be able to name a few essential biological roles of metal ions present in living systems, including Fe, Ca, Zn, Mn, Cu, Co, Mg, Na, and K
Understand association constants & rate constants for metal binding to proteins, and do basic calculation with them
Understand which kind of binding site can bind which metal ions, and how different metal ions differentiate from each other
Understand the notions of first and second coordination sphere in metalloproteins
Differentiate the bound metal pool from the “free” metal pool
Know different mechanisms by which metal ions penetrate in living organisms and cells and are stored
