Learning objectives
The aim of the course is to provide the students with the thermodynamic concepts necessary to the knowledge and the understanding of the interconversion of the energy in biological systems (bioenergetics) as well the ligand-biomacromolecule interactions. The molecular basis of protein-ligand complex ormation will be provided together with the biochemical basis of drug action.
Learning results
At the end of the course, the student will have acquired extensive knowledge and deep understanding of the interactions between ligands and biological macromolecules. Such knowledge will be applied to the interpretation of the molecular mechanisms of drug action.

Teaching methods
Modul of Biological Physical Chemistry (6 CFU) Prof. C. Compari
- During the oral lesson, integrated with informatic tools and the support of multimedia, will present the basic concepts of physical chemistry with particular emphasis on biological applications .
Modul of Pharmaceutical Biochemistry (6 CFU) Prof. S. Bruno
- Oral lessons integrated with informatic tools and the support of multimedia
The course will be held through lectures to Students either in the classroom (“in presenza”) or in synchronous-streaming (“in telepresenza”) on the Teams platform. Therefore, the opportunity of Student/Teacher interaction will be preserved both face to face and remotely, by the simultaneous use of the Teams platform.
Lectures will be supported by slide presentations, which will be available to students on the Elly platform (https://elly.medicina.unipr.it).
Assessment methods and criteria
A final oral examination will have to be passed, during normal examination sessions.
The questions will have the purpose of establishing the level of knowledge and understanding of the course content, in relation to the educational goals.
The final mark of the examination will be the mean of the marks obtained in the individual modules.
In case of the persistence of the health emergency, the exams will be conducted remotely, as follows:
remote oral questions, through the Teams platform (guide http://selma.unipr.it/).
