BIOCHEMISTRY 1. Constitutive elements of the living matter: polymeric structure of the biological macromolecules. 2. Protein structure and function: aminoacid classification, buffering power, peptide bond, levels of protein structure; fibrous and globular proteins; hemoglobin and myoglobin: structure, function, factors influencing the oxygen bond; hemoglobin variants; enzymes: classification, role in the chemical reactions, regulation of the enzymatic activity. 3. Vitamins: hydro- and lypo-soluble vitamins; co-enzymes. 4. Bio-energetics: metabolism; chemical transformations in the cell; spontaneous and non-spontaneous reactions of the metabolic reactions; ATP as “energy exchange coin”; biologically relevant redox reactions. 5. Carbohydrates structure and metabolism: mono- and disaccharides; polysaccharides; glycoconjugates; glycolysis and its regulation; gluconeogenesis; hints of the penthose phosphate pathway; synthesis of the glycogen. 6.

Examination Methods

The exam consists of 4 written tests, one for each module, based on all the issues covered throughout the course. Tests can be passed separately as long as they are taken within the same academic year. For each academic year, 6 periods are available to take the exams: 2 in the Winter Session at the end of the course, 2 in the Summer Session and 2 in the Autumn Session. In order to gain access to the biology test, students must have first discharged any training debts relating to the minimum biology, chemistry and physics knowledge.
To pass the exam, students must get a score of not less than 18/30 in each test. The final mark (/out of 30) willl derive from the weighted average over credits of each single test score. Students can retire or refuse the proposed score: in such case, any partial credit will be canceled and the students shall enroll again for the whole examination (all the 4 tests).
