Obiettivi formativi
The course will introduce the basics of Organic Chemistry necessary to obtain a full understanding of the chemical basis of biological molecules and their interactions.
Risultati apprendimento attesi
At the end of this class , the students are expected to be able to understand the chemical basis of the structures and interactions of biological molecules (DNA, RNA, proteins) that will be the main subject of study of the other courses of the degree, and to be able to apply the knowledge acquired to the interpretation of the results of the bioinformatic analysis of biomolecular data.
