After the course it is expected that the students know the biochemical and spectroscopic concepts needed to characterize biological systems at the structural and spectroscopic levels. With a strong experimental component, in an environment very similar to a research laboratory, it is intended that students:
- develop the ability to understand and select appropriate techniques and methodologies in the study of a particular biological system
- cultivate a critical analysis and interpretation, in an integrated manner, all experimental data
The writing and discussion of a final report seeks students to develop ability to write a scientific manuscript and acquire training in the critical review of the scientific literature and skills in presenting scientific papers.

All the information about the course is accessible through the dedicated web page on CLIP platform. In this site all pdfs files of the lectures presentations, laboratory protocols and exercises will be available.
Students will be admitted to evalutaion of the theoretical component with frequency.
The frequency is obtained by:
- compulsory attendance of all laboratory sessions
- delivery of the laboratory report (1/group)
Evaluation of the practical component:
- Punctuality, preparation and execution of laboratory classes
- delays to laboratory classes or non-preparation will contribute -0.5 values to the final grade of the practical component
- Evaluation of the laboratory report
The assessment of the theoretical component:
Will be carried out by performing three theoretical tests, with a contribution of 45 %, 45 % and 10 %, respectively.
40 % practical component + 60 % theoretical componente
- Approval to the curricular unit requires a final grade ≥ 9.5 in each of the components, theoretical and practical.
- All scores (tests and evaluation of the practical component) will be rounded to the tenth.
- On appeal exam (recurso or other) only the theoretical component will be evaluated.
- Improvement of the final grade will contemplate only the theoretical component.
