Molecular mechanisms and biostrasformation

A.Y. 2019/2020
Overall hours
Learning objectives
The course aims to provide notions that allow the student to acquire the knowledge related to the main biochemical-molecular aspects that are the basis of the biotransformation processes of xenobiotics and of the related molecular mechanisms of biotransformation regulation.
Expected learning outcomes
At the end of the course, the student must be able to illustrate the main metabolic pathways of biotransformation, and to have developed a critical awareness that may be useful in reading and interpreting scientific articles that will be also objective of the final discussion.
