Home E Syllabus and Course of Studies E General Chemistry for Biosciences

Theory: 4 hours/week | Practicals: 2 hours/week | ECTS Units: 6

Content – Aim of the course

This course is an introduction to the basic principles of chemistry, that form the scaffold for the better understanding of biochemical reactions. Students are introduced to the basic principles of atom structure and the modern quantum theories of the chemical bond. The types of intermolecular interactions and how these affect the behavior of various systems is also discussed. Finally, the course includes the study of various chemical equilibria between molecules and ions (ionic equilibria and redox reactions) and chemical kinetic data and chemical thermodynamics.
