Obiettivi formativi
The course will provide students with a basic understanding of the chemical fundamentals of the organic natural products and of their role as biologically active compounds in the interrelationship among living organisms to facilitate their communication in and with the environment.
This multidisciplinary course is focused on the impact of natural products and xenobiotics in the context of human and animal health, nutrition and agroecology.
Risultati apprendimento attesi
At the end of the course, the student will acquire a broad knowledge of the chemistry of life in terms of species adaptation to the environment. He/she will also acquire the basis of the application of technologies for the environment and the impact they have on health, nutrition and agroecology.
