Course abstract

In the study course "Organic Chemistry II" acquires knowledge about the structure, properties and distribution of the main components of food - lipids, carbohydrates, nucleic acids and proteins in natural and food products. In the laboratory works the proof of properties of natural substances and methods of separation and purification of chemical compounds are mastered.

Learning outcomes and their assessment

After the course studies the student will have:
in-depth knowledge of the structure and properties of lipids, carbohydrates, nucleic acids, proteins of food-forming compounds - lectures and tests;
skills to check the properties of lipids, carbohydrates, methods of extraction and purification - laboratory works;
competence was the ability to use independently acquired knowledge and skills to explain various processes related to organic and natural substances - independent and laboratory work.

Requirements for awarding credit points

Passed the written exam

Description of the organization and tasks of students’ independent work

The student, in accordance with the requirements, must prepare protocols of laboratory work and solve homework tasks before tests.

Criteria for Evaluating Learning Outcomes

In order for a student to take the exam, all tests and laboratory work must be included. The exam is passed successfully (at least 4 points), if at least 40% of the total points are obtained.
