Presentation
Physical biochemistry is a course that applies the mathematics and physical principles of chemistry to important problems in biochemistry, biology, and medicine. It deals with the theory, techniques, and methodology used to study the physical chemistry of biomolecules. It also deals with mathematical approaches to the analysis of biochemical reactions and modeling of biological systems. It provides insight into the structure of macromolecules and how the chemical structure influences the physical properties of a biological substance. Topics include separation and characterization of macromolecules (chromatography, electrophoresis, sedimentation equilibrium), macromolecule identification methods (mass spectrometry), methods of structural determination of macromolecules (circular dichroism, X-ray diffraction, NMR) and macromolecule stability methods (calorimetry and fluorescence spectroscopy).

Objectives
Objectives
The CU of Biophysical Chemistry aims at transfer knowledge in the techniques more used in the characterization of proteins. More specifically, techniques that are used in protein purification, sedimentation, mass spectrometry, titration and scanning calorimetry, principals of protein folding, and techniques that can be used to obtain information on the structure-function of proteins. At the end of the CU, the students should master the principles of these techniques, such that the student should be able to develop an efficient procedure to separate the protein of interest from a complex mixture, and identify the experimental techniques that can be used in its basic biochemical characterization, and to obtain information about its stability and structure-function relationship.

Teaching methodologies
Teaching methodologies
The UC programmatic contents are taught through powerpoint presentations with illustrative images to capture and motivate students, and for a better understanding and organization of learning materials. It also includes practical exercises for applying theoretical concepts and study visits to research centers so that students can visualize the instruments and understand their applications in different scientific areas.

Ensino presencial com aulas teóricas e laboratoriais: As aulas teóricas são aulas magistrais de frequência voluntária seguindo o programa definido. As aulas laboratoriais são aulas tutoradas, orientadas por um docente, e de frequência obrigatória, destinadas a aplicar as técnicas e os princípios teóricos.
Os requisitos para aproveitamento são os seguintes:
A. Avaliação contínua
Frequência obrigatória das aulas laboratoriais.
Classificação prática igual ou superior a 9,5 valores (avaliação contínua do desempenho dos alunos, 30% na classificação final).
2 frequências teóricas, média com ponderação de 70 % (classificação final igual ou superior a 9,5valores).
B. Exame final
Exame com 2 componentes prática (30%) e teórica (70%). Nota igual ou superior a 9,5 valores em cada componente.
Isenção de repetir uma das 2 componentes em caso de nota igual ou superior a 9,5 valores obtida para essa componente em avaliação contínua ou exame final anterior.Teaching includes lectures and practical classes. The lectures (explaining the main concepts) are of facultative attendance, following the defined syllabus. Practical laboratory classes are mandatory and are carried out under the guidance and orientation of a Professor, in order for students to practice the techniques and its principles taught in the lectures.
Minimum requirement to pass:
A. Continuos evaluation
Attendance of practical classes.
Laboratory minimum classification of 9.5 values ( corresponding to 30% of the final classification).
2 mid-term written exams, average with 70% weight (minimum final classification of 9.5 values ).
B. Final examination
Written examination with 2 components: practical (30%) and theoretical (70%). Minimum classification of 9.5 values in each component.
Students with a minimum classification of 9.5 values in one of the components in a previous evaluation (continuous or written evaluation) are exempted from repeating that part of the exam
