Course abstract

Fundamentals of Biochemistry characterize the general principles of metabolism in human body, digestion of food compounds, the role of water, vitamins and mineral substances in food, the main accent is directed toward the exploration of the interconnection between processes of metabolism and its regulation in organism.

Learning outcomes and their assessment

•extensive knowledge about properties and structure of lipids, carbohydrates and proteins and the human body metabolism forming food products and about the biochemical processes and the biochemical regulation in the human body - Tests;
•skills to use the obtained theoretical knowledge about lipids, carbohydrates, proteins in other study courses; skills to use theoretical and practical knowledge to carry out professional and research activities - laboratory works;
•competence - the ability to independently access, select and analyze information about lipids, carbohydrate, protein and the human body metabolism in different food products; to use information, to make and explain decisions and solve scientific and professional issues – colloquium.
