BIOPHYSICAL CHEMISTRY

Course objectives

The issues developed in this course concern the physico-chemical properties of biological systems and the spectroscopic and structural techniques, theoretical and experimental, that allow their characterization. Theoretical models and related proofs regarding such complex systems will be treated. As regards essential knowledge, the student should acquire skills on physico-chemical properties of biological systems and the experimental and theoretical methodologies more used to investigate them. In this respect, the student should know the main thermodynamic and kinetics processes concerning biological systems, the involved quantities and functions and their macroscopic and microscopic physical meaning. It should be clearly understood the approximations and the hypothesis at the base of the models used. It is expected that the student will show the capacity of choosing formulations and equations suitable to solve quantitative problems and methods proper to investigate the proposed systems (first and second Dublin descriptors). The capability of analyzing the problems, of synthesis and logical coherence will be evaluated as well as the ability to adopt a correct language (third and fourth Dublin descriptors). Finally, considering that the course belongs to the graduate degree (second cycle), competence on applications of techniques to solve biological relevant problems from a chemical-physical point of view will be appreciated.

Prerequisites
For a better learning of the topics proposed in this course, the following basic skills are required: classical thermodynamics (first, second and third principles, chemical equilibrium, thermodynamics of solutions, first-order transitions), statistical thermodynamics (principles, Gibbs ensembles, microcanonical and canonical partition functions), basic concepts and principles regulating the chemistry of biological processes ,classical spectroscopies (vibrational, electronic, fluorescence, nuclear magnetic resonance). In addition, the student should be familiar with the basic knowledge of mathematics (derivatives and partial derivatives, differentials, integrals and differential equations, simple series) and physics (mechanics, electrostatics and electromagnetism).

Teaching mode
The course is composed of 72 hours devoted to the theoretical treatment of the topics proposed in the program (theoretical models, mathematical proofs, applications and limits of the obtained equations, techniques and methods of investigations of disperse systems) and to discuss the investigation of significant systems (choice of methodology and techniques). In addition, the applications in the field of biophysics and chemistry applied to biological systems will be presented by participation at selected seminars and in-depth studies of selected biological and biochemical processes.
Frequency
In person
Exam mode
The student will be evaluated by an oral exam in which the student should discuss the physical-chemical properties of biological systems, the related models, and the experimental methods and techniques used for their investigation (principles of techniques and applications). The capability of analysis, making judgment and communication will be also evaluated. Simple and exemplary systems will be discussed to evaluate the student skills to frame the chemical problem in the correct context and choose the most suitable methodologies of investigation. In addition, the student should be capable of discussing the possible applications of the investigated systems in the most advanced fields of biological interest.
