    LANGUAGE Italian
  • SEMESTER 2° Semester
    MODULES This unit is a module of:



    Upon completion of the course, the student will:

        know in depth the structure and function of proteins, demonstrating an understanding of how properties influence their function in physiological states and disease;
        know the main types of biochemical reactions that occur within organisms, to explain their mechanisms, energy changes, the role of enzymes and regulatory mechanisms;
        know the main metabolic pathways, their functional significance and regulatory mechanisms and have understood the biochemical specificities of different tissues and the metabolic interactions between organs;
        apply acquired knowledge of general mechanisms of metabolic regulation to explain cellular and organismal responses in response to the action of hormones, during fasting and fed state and their alterations in some disease states used as models (diabetes, cancer cells);
        critically evaluate how biochemical alterations due to disease states can be analyzed through laboratory investigations;
        know how to describe biochemical processes adequately and with correct terminology for identification of molecules.

    All slides used during lectures and other lecture materials will be available on Aulaweb. In general, the notes taken during the lectures and the material on Aulaweb are sufficient for exam preparation.

    The book listed below is suggested as a supporting text, but students may still use other college-level Biochemistry texts as well, as long as they are editions published within the last 5 years. Copies of the text are available for reference at the School of Medical and Pharmaceutical Sciences Library

    Nelson DL and Cox MM Lehninger's Principles of Biochemistry, Zanichelli



    Exam Board

    SANTINA BRUZZONE (President)

    GIANLUCA DAMONTE (President)



    ELENA ZOCCHI (President and Coordinator of Integrated Course)

    Class schedule

    All class schedules are posted on the EasyAcademy portal.



    The examination consists of an oral test. The final grade will be calculated on the basis of the weighted average of the grades obtained in the Biochemistry Propaedeutics (6 CFU), Biochemistry (10 CFU) and Clinical Biochemistry (1 CFU) portions. The Biochemistry and Clinical Biochemistry tests must be taken in the same roll call. Should the student fail one of the two tests, he/she will necessarily have to repeat both at a later appeal.

    There will be 3 exam appeals available for the winter session (mid-January- February) and 4 appeals for the summer session (June, July and September). Extraordinary appeals will not be granted outside the periods specified in the course regulations, except for out-of-school students.


    Details on how to prepare for the exam and the degree of depth of each topic will be provided in the course of the lectures.

    The oral examination will cover the topics covered in the lectures and will aim to assess not only whether the student has achieved an adequate level of knowledge, but whether he or she has acquired the ability to critically analyze biochemical problems that will be posed in the examination, including from a pathophysiological perspective. The student will also be required to draw the structure formulas of biomolecules and metabolic intermediates, identifying the types of reactions involved and the resulting energy changes. The student will also be required to demonstrate the ability to describe biochemical processes clearly and with correct terminology.
