Bio-organic chemistry

BIO-110 / coefficient 5

Enseignant: Ferreira De Sousa Correia Bruno Emanuel

Langue: Anglais

Summary

The aim of the course is to provide a chemical understanding and intuition to decipher and predict chemical processes in living systems.

Content

The course will first introduce fundamentals of organic chemistry, including substance classes, nomenclature, stereochemistry, as well as the fundamental relationships between structure and reactivity. Knowledge of selected compound classes and their most important reaction types such as acid-base reactions, substitutions, additions, eliminations, redox chemistry will be covered using model reactions from classic organic chemistry. Moreover, the course includes projections on natural processes in biological systems, providing a toolbox to understand complex biological processes of life on a molecular level. The course continues with the fundamental principles that enable chemistry inside cells, such as molecular recognition patterns and enzymatic reactions. Throughout the semester, students will gain insights into analytical methods and explore computational tools to facilitate scientific research and discovery. Finally, we will use and combine the learned principles to shine light on key biochemical processes and applications.
