The course is divided into two modules. In module 1, the main topics of chemistry are explored through the study of functional groups, properties and reactions for the main classes of organic compounds and coordination compounds. A special focus is devoted to complex chemical structures: polymers and (bio) macromolecules. In module 2, the functional and regulatory properties of these biological macromolecules are then discussed in relation to the main metabolic pathways in living organisms.
The course aims to provide an in-depth chemical culture through the study of the main functional groups and classes of reactions in organic chemistry. It also provides fundamental knowledge on the structure and metabolism of biomolecules, with particular attention to kinetic and thermodynamic aspects.
The aim of the course is to provide an in-depth knowledge of the structure, reactivity and properties of complex molecules, starting with the classification and structure of the main functional groups in organic chemistry and the reaction pathways for the interconversion of these class of compounds. Students will learn the structure of the main synthetic macromolecules and natural macromolecules (lipids, proteins, carbohydrates, nucleotides) and their main anabolic and catabolic pathways, with particular attention to the role of enzymatic regulation and kinetic and thermodynamic considerations. Students should be able to correlate the signaling pathways activating different metabolic responses in different organs, with a focus on (dys)functional integration between different human organs.

Oral exam covering all the topics of the program, or two separate partial oral tests, corresponding to the topics of Chemistry, first, and Biochemistry.
At the end of the course, the student is required to demonstrate that the the learning outcomes have been reached, having acquired operational skills and methodology for approaching problems related to the properties, structure and reactivity of complex biomolecules, especially in relation to applications of technological and medical-biological interest. The student will be able to connect different areas of the subject and to describe the correlation among different metabolic pathways.
