Learning objectives

The course aims to provide the basic concepts of Organic Chemistry that can be applied to the molecular description of biological phenomena and the modification of these to obtain biotechnological applications. In particular, the course will provide elements for understanding the chemistry of the main biological macromolecules (peptides, oligonucleotides, oligo- and polysaccharides) and their transformations, and the biological properties and origin of secondary metabolites. Case studies will also be presented where the application of such knowledge has led to important industrial progress, with particular attention to modern life-related nanotechnologies.

Study skills:
The course will provide the acquisition of a formally correct language; the ability to express the content in a clear and immediate way will be stimulated; the links between the different parts of the course and how they contribute to the overall understanding of the biological systems will be emphasized.

Application of knowledge:
The course aims also to provide the tools to interpret rationally and at the molecular level the main properties of biological macromolecule,s and biological pathways leading to the production of secondary metabolites. Such compounds are found only in specific organisms or groups of organisms and are the expression of the individuality of the species. It also stimulates the student's understanding of events that had previously been addressed only in a phenomenological way.
The course also aims to provide students with tools for interdisciplinary and interdisciplinary research on biotechnology and chemistry applied in this field and to discuss / communicate with chemists colleagues.

Assessment methods and criteria

The requested knowledges for a successful examination are: ability in critically facing the study of scientific literature even in a research context; ability in applying the knowledges in basic Organic Chemistry and Instrumental techinques to solve problems of biotechnological interest also in interdisciplinary contexts; ability in communicating with an appropriate and unequivocal language the acquired knowledges. The student must also demonstrate to be able to continue in autonomy the study of the molecular aspects of biotechnologies; to have a proper and detailed knowledge of the properties of principal classes of biomolecules and secondary metabolites, of their chemical behavior, the methods for their characterization and purification.
The written test consists of 10 questions. In order to pass, 6/10 questions have to be correctely answered or, alternatively, if at least 60% of the total content expressed is correct and exhaustive.
The written test is followed by an oral examination to further evaluate the knowledge emerged from the written test.
