Course objectives
This course is an extension of the Biochemistry I. It carries next important knowledges about biochemical reactions in living cell. It describes the metabolism of proteins and nucleic acids, proteosynthesis and its regulation, basic metods of study and practical applications. It describes also other functions of proteins, carbohydrates and lipids, some special metabolic pathways and indicates the connections between chemical reactions and physiological features in an organism.
Students will acquire important knowledges here, necessary for full understanding of basic principles of biochemical basis of life, and required for next special courses in biochemistry and molecular biology.
Learning outcomes
Students will acquire important knowledges here, necessary for full understanding of basic principles of biochemical basis of life, and required for next special courses in biochemistry and molecular biology. They will learn metabolism of nitrogen containing compounds, genetic code, principles of replication, transcription and tranlation.
