Programma

The Bioenergetics and Metabolism module (Prof. Alessandra di Masi) will cover the following topics: bioenergetics and types of biochemical reactions, glycolysis, gluconeogenesis, pentose phosphate pathway, principles of metabolic regulation, citric acid cycle, fatty acid catabolism, amino acid oxidation and urea cycle, oxidative phosphorylation.

The practice module of the course of Biochemistry is NOT MANDATORY and includes three laboratory experiences, each lasting 2 hours. The topics of the experiences are:
1. Protein quantification by Bradford method.
2. Separation of proteins by SDS-PAGE method and determination of their molecular weights by migration distance.
3. Characterization of the enzymatic activity of lactate dehydrogenase.
The results obtained will be analyzed and discussed together with the teacher during a frontal lesson in the classroom.

RECEPTION TIME: Monday 10 am

Modalità Erogazione

The practice module of the Biochemistry course includes three laboratory experiences, each lasting 2 hours. The experimental data obtained during the practical experiences must be analyzed by the students using appropriate software (Excel). The results obtained will be discussed together with the teacher during a classroom lectures.

Modalità Frequenza

Attendance is mandatory for classroom lectures. Attendance at laboratory exercises is optional.

Modalità Valutazione

Participation in the three laboratory experiences is mandatory in order to take the Biochemistry exam. At the end of the laboratory experiences attended (2 out of 3 mandatory), the student is required to analyze the experimental data obtained using appropriate software (Excel). The student will be required to write a short report reporting the data obtained in each experience attended.
