Learning outcomes
Xenobiochemistry studies the metabolic conversion of xenobiotics, different natural compounds, drugs and environmental contaminants. Xenobiochemistry explains pharmacological and toxicological consequences of presence of xenobiotics in living organism. Many natural compounds may be characterized as poisons and these are subject of interest of toxicology. Poisons are chemical substances harmful to living organisms including humans. These chemicals are produced by all forms of living organisms: bacteria, fungi, plants and animals or are produced by humans.
Final Competences: -To have knowledge of and to have insight in theme of xenobiochemistry and toxicology -To have knowledge of and to have insight in the general principles toxicology, fate of toxicants in organism, absorption and distribution, biotransformation, bio-active metabolites, elimination, acumulation. -To have knowledge of possible mechanism of toxic action. -To have knowledge of special toxicity effects: teratogenicity, hepatotoxicity, nephrotoxicity, immunotoxicity, neurotoxicity. -To have knowledge of principle of analytical methods in toxicology.
Knowledge from courses: Cell biology, Molecular Biology, Biochemistry

Assessment methods and criteria
Essay, Student performance assessment, Combined exam, Test, Interim evaluation

The student must actively participate in the practical part, prepare an essay on a selected topic related to xenobiochemistry and toxicology, and pass the tests. Knowledge of toxicological principles and xenobiochemical pathways will be needed to pass the test.
