Annotation -
General Biochemistry provides the basics necessary for further study of follow-up biochemical disciplines in the study program of Pharmacy at the Faculty of Pharmacy. It is based on knowledge of biology, organic and bioorganic chemistry, and human morphology and physiology. It explains metabolic pathways, their regulation, principles of thermodynamics and enzymatic catalysis and includes the basics of proteosynthesis and xenobiochemistry. Topics: Proteins, enzymes, enzyme kinetics, basics of thermodynamics of biological systems, metabolism of polysaccharides, lipid metabolism, amino acid metabolism, citric acid cycle, respiratory chain and oxidative phosphorylation, nucleotide metabolism, transport mechanisms and compartmentation, heme biochemistry, cell-cell signalling, an overview of regulatory mechanisms of metabolic pathways, the basics of xenobiochemistry.
