Objetivos
At the end of the curricular unit (UC) the student is expected to have theoretical knowledge about: - the structure and organization of the different cellular constituents in the different types of cells; - the function and structure of the most important biomolecules, namely, nucleic acids (RNA, DNA), carbohydrates, lipids and proteins; have notions of enzymatic kinetics and enzymatic assays.
In addition to acquiring theoretical knowledge, the student should know how to apply it in a laboratory context: - preparation of typical buffer solutions for biochemical assays, - biomolecule purification techniques, namely chromatographic and ultrafiltration techniques, - biomolecule assay techniques (carbohydrates, proteins, nucleic acids), mastering colorimetric methods and spectrophotometric analyses, - analytical techniques for protein separation (acrylamide gel electrophoresis), - analysis and assay methods based on direct and indirect enzymatic assays.

Métodos de ensino e atividades de aprendizagem
The UC assessment is considered as a whole, integrating the theoretical and practical components. In the theoretical component, an expository-participative methodology is used, privileging the contribution of students. Theoretical-practical classes will encourage students' ability to work independently in solving exercise sheets on the themes presented in the theoretical classes.
In the laboratory practical component, experimental works are developed that cover the contents of the UC and aim to provide the student with skills in the scope of "know-how".
The theoretical/theoretical-practical component is evaluated through tests during the semester, and the experimental work is evaluated through the elaboration of reports using updated and reference bibliography. The theoretical component has a weight of 50% and the practical component another 50% in the overall assessment.
