Is part of:
Knowledge and understanding: the student must acquire specific and targeted knowledge on general chemistry, such as the structure of the inorganic and organic matter, the laws that govern the chemical transformations and the structure and nature of the main classes of organic molecules with particular attention to those of biological interest. The course also aims to help the student to understand the main processes of the cellular metabolism. The module is oriented to the description of the structure and function of the main classes of biomolecules (proteins, nucleic acids, sugars and lipids), as well as the presentation of the complex interplay between the metabolic pathways (catabolic and biosynthetic)
Apply knowledge and understanding: the student must demonstrate skills to carry out chemistry exercises related to lecture topics. The student should be able to describe the interconnections between macromolecular structures and their function, the correlation that exists between the different metabolic pathways within a cell, organ or tissue, processes and mechanisms with which these metabolic pathways are regulated and how alterations of these processes can be related to pathological dysfunctions of a cell and an organism
Making judgements: the student must be able to critically discuss the different aspects of metabolic pathways and their correlation with pathological dysfunctions.
Communicative skills: ability to use a scientific lexicon .
Learning skills : the student must demonstrate to have faced the systematic study of chemistry and biochemistry autonomously and profitably and to be able to transfer the theoretical notions in real application situations
Mathematical capacity of simple numerical calculation for example solution of first and second degree equations and proportions.

Amino acid catabolism: metabolic fate of amino groups, nitrogen excretion and urea cycle, amino acid degradation.
Bioenergetics: The citric acid cycle and its regulation, oxidative phosphorylation, electron flow and ATP synthesis.
Hormonal regulation and integration of metabolism
Lectures with the support of slides. At the end of the course, a few hours will be held to carry out chemistry exercises related to the topics discussed and which will provide an example of "type" exercises proposed during the exam.
The course slides will be uploaded to the Course's Teams platform. Attending and non-attending students may request also supplementary teaching material and information about the course and exam dates to the teacher by institutional email address (emarsich@units.it).
The written exam consisting of 3 open questions and 2 chemistry exercises. Duration of the test 2 hours. The assessments and the final mark are given as thirty points. Both the open questions and the numerical exercises are worth 6 points each. A score lower than 6 is also provided - from 5 points to 1 point if the answer is incomplete, only partially correct and the argument is presented in a convoluted manner with little or no knowledge of the language, 0 points if the student does not answer or does not demonstrate acceptable knowledge of the content The dates for the module examinations, the registration of the student for the partial examination and the notification of the grade to the student are managed on the ESSE3 platform
This course explores topics closely related to one or more goals of the United Nations 2030 Agenda for Sustainable Development (SDGs)
