Course abstract

The aim of the course is to describe the general principles of metabolism in the human body, the digestion of food compounds, the role of water, vitamins and minerals in food, the main emphasis is on learning the interrelationships between metabolic processes and their regulation in the body.

Learning outcomes and their assessment

Knows about the properties and structure of lipids, carbohydrates and proteins and the metabolism of the human body, which make up food products and about biochemical processes and biochemical regulation in the human body - Tests;
• is able to use the acquired theoretical knowledge about lipids, carbohydrates, proteins in other study courses; knows how to use theoretical and practical knowledge to perform professional and research activities - laboratory work;
• competence – able to independently access, select and analyze information about lipids, carbohydrates, proteins and the metabolism of the human body in various food products; use information, make and explain decisions and solve scientific and professional questions - colloquium.
