MM: BIOCHIMICA
------------------------
PREPARATORY CHEMISTRY (several notions are included in the basic knowledge required). 1. Atomic structure and periodic properties of the elements: matter composition, atom, atomic particles; atomic theory; quantum numbers, and orbitals; electronic configuration, periodic table and chemical reactivity of the elements; electronic affinity, electronegativity. 2. The chemical bond: molecules and ions; ionic and covalent bond; intermolecular forces; hydrogen bond. 3. Solutions and acid-base reactions: concentration of the solutions, acid-base theories of Arrhenius and Brőnsted-Lowry; hydracids, hydroxides, oxyacids; acid-base reactions; pH and buffer solutions. 4. Organic chemistry notions: carbon atom properties; hybrid orbitals; organic compounds classification: functional groups; hydrocarbons; alcohols, ethers, thiols, amines, aldehydes and ketones; carboxylic acids, esters, anhydrides. 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. Citric acid cycle and oxidative phosphorylation: mitochondria; acetyl-CoA synthesis; citric acid cycle control; respiratory chain and electron transport; ATP synthesis. 7. Lipids structure and metabolism: structural lipids and biological membranes; cholesterol; stock-reserve lipids; lipids digestion and fatty acid β-oxydation; keton bodies formation; hints of fatty acids biosynthesis. 8. Aminoacid metabolism: hints of gluco- and keto-forming aminoacids; transamination and oxidative deamination; the urea cycle. Frontal teaching is the exclusive method adopted in this Course.

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).
