Learning outcomes

The aim of Biochemistry course is focused on understanding the molecular bases of how biological systems work and the structure-function relationships of macromolecules, both in physiological and in pathological condition. The course aims to introduce the main metabolic pathways and their regulations at the molecular, cellular and tissue levels, integrating chemical, physiological and pathological aspects of human biochemistry, in order to provide students with biochemical knowledge useful in the practice of dentistry.

Syllabus

Structure and classification of amino acids. Structure of the peptide bond. Secondary structures (alpha helix, beta sheet, triple helix of collagen). Tertiary and quaternary structures of proteins. Structure and function of fibrous proteins: alpha keratin, actin-myosin, elastin. Structure and function of proteins that bind the oxygen, saturation curve of hemoglobin for oxygen, cooperative effect, Bohr effect, 2,3 bisphosphoglycerate, pathological hemoglobins. Enzymes: examples of enzyme catalysis. Enzyme kinetics, maximum speed, Michaelis constant. Enzyme inhibition: competitive, non-competitive, allosteric. Regulation of enzyme activity by phosphorylation. Vitamins and co-enzymes.
Introduction to metabolism. Electron transport chain, theory chemo-osmotic, oxidative phosphorylation by rotational catalysis.
Digestion of carbohydrates, glycolysis, energy balance and its regulation, lactic fermentation. Gluconeogenesis, glycogen synthesis and glycogen lysis. Hormonal regulation of blood sugar. Pentose phosphate pathway.
Oxidative decarboxylation of pyruvate, the citric acid cycle and its regulation.
Catabolism of ethanol and its effects on hepatic metabolism. Cycle nutrition / fasting, metabolic dis-regulation in some human diseases.
Digestion of lipids, transport of lipids in the blood, lipoproteins.
Cytosolic activation of fatty acids, carnitine transport into mitochondria.
Beta oxidation of fatty acids. Ketogenesis, fatty acid synthesis, cholesterol metabolism.
