Course description and learning objectives
The course of Biochemistry and Applied Biochemistry is part of the molecular preparation of the student in Biology and Biotechnology. The course is organized in two parts: the first (Biochemistry Module) is aimed to introduce the student into the understanding of the structure-function relationships of biological macromolecules, of the molecular mechanisms of the biological processes and their regulation. The description of the metabolism will be performed both at the qualitative and quantitative level. The second module (named Applied Biochemistry) is aimed to describe the theoretical principles and the practical applications of the main preparative and analytical methodologies used in the biochemical and molecular biology research fields, with specific emphasis to the structural and functional study of the enzymes.
The course is based on theoretical lessons and experimental lab activities.

Final assessment
Biochemistry Module:
The examination is organized in a written test concerning quantitative biochemistry and knowledge of macromolecules (four open questions and two exercises). Passed the written part, the student can access the oral examination, which is aimed to verify the knowledge of the metabolism.
Applied Biochemistry Module:
Written test (3-4 open questions and about 10 multiple-choice questions) concerning the theoretical basis of the biochemical techniques. The lab activity will be evaluated through a written scientific report of the experimental activities.
