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.
Programma e organizzazione didattica

Edizione unica

Secondo semestre
Teaching methods
Asynchronous lessons will be made available (videolessons consisting of recording the teacher's desktop with audio commentary), organized to cover the topics of each lesson of the course. The recorded lessons will be made available to students on the ARIEL teaching platform throughout the semester and uploaded to the site according to the teaching schedule. Furthermore, synchronous meetings with students will be organized periodically, using the Microsoft Teams platform, to provide clarifications and insights on teaching topics and answer students' questions.

Learning assessment procedures and assessment criteria
The exam will take place in oral form using the Microsoft Teams platform and will be aimed at ascertain:
- the achievement of the course objectives in terms of knowledge and understanding.
- the ability to apply knowledge and understanding and verify the autonomy of judgment through the discussion of the topics covered by the lessons.
- the mastery of the specific language relating to the field of biochemistry and the ability to present the topics in a clear and logical way, with the necessary links to the content of other courses of the degree course.
