Learning objectives
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.
Expected learning outcomes
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.
Single course

This course can be attended as a single course.

Assessment methods and Criteria
Preliminary short test (n=10 multiple choice quizzes, minimum correct answers to be admitted to the oral session: n=6 out of 10).
Oral exam (20 min approximately).
Students will be asked to discuss a personal written report on the analysis of two case-studies taken from the scientific literature and based on the topics discussed during the classroom lessons. Subsequently, the student will be asked to respond to questions from the assessment commission, questions that can be related to the report/presentation content, to specific topics included in the course program, of combinations of the two.
The report must be sent by a single e-mail addressed to the Profs Verotta, Marzorati and Beretta (a single e-mail, not individual separate e-mails) no later than one one week before the exam date.
The final mark is represented by the sum of n=10 points earned by the student for each section (written report: 10 points; report presentation: 10 points; questions on course sub-sections: 10 points).
Presentation files can be uploaded during the assessment session.
