Contents

BIOCHEMISTRY
Introduction to biochemistry (biomolecules; water effect on dissolved biomolecules; weak interactions in aqueous systems).
Structure and function of carbohydrates (monosaccharides, disaccharides, polysaccharides; proteoglycans, glycoproteins and glycolipids).
Structure and function of lipid (fatty acids, storage lipids, structural lipids in membranes, cholesterol; lipids with specific biological activity; fat-soluble vitamins; lipoproteins).
Structure and function of proteins (aminoacids and peptide bond; peptides and proteins; primary, secondary, tertiary and quaternary structure; alfa-keratin, collagen and elastin; myoglobin and haemoglobin; oxygen and carbon dioxide transport; immunoglobulins).
Structure and function of water-soluble vitamins and their coenzymatic derivatives.
Enzymes (apoenzyme, cofactors and coenzymes, holoenzyme; enzyme-substrate complex and active site; enzymatic reaction mechanisms; enzyme kinetics; enzyme classification; several factors that affect the rate of enzyme-catalyzed reactions; enzyme activity regulation).
Introduction to metabolism (endergonic and exergonic reactions; catabolic and anabolic pathways; energy production and consumption in metabolism; role of ATP and other phosphorilated compounds; metabolism integration and regulation).
Carbohydrate metabolism (glycolysis and gluconeogenesis; alcohol and lactic fermentations and pyruvate oxidation to acethyl-CoA; the pentose phosphate pathway; glycogen lysis and glycogen synthesis).
Lipid metabolism (digestion, mobilization and transport; fatty acids: activation and transport into mitochondria; β-oxidation of saturated/unsaturated fatty acids, with even/odd number of carbon atoms; propyonyl-CoA fate; ketones bodies: formation and utilization; biosynthesis of cholesterol and fatty acids).
Aminoacid metabolism (transamination and oxidative deamination; amino acid carbon skeletons oxidation: glucogenic and ketogenic amino acids; metabolic fates of amino groups;; urea cycle; amino acid converted to biological amines by decarboxilation).
Energy production (citric acid cycle, oxidative phosphorilation: mitochondrial respiratory chain, mitochondrial electron flow coupled to proton gradient; ATP synthase complex; shuttle systems for mitochondrial oxidation of cytosolic NADH).
