Course abstract

In the study course "Organic Chemistry" students acquire knowledge about the structure, properties and distribution of organic compounds distributed in food - alcohols, phenols, aldehydes, ketones, amines, carboxylic acids and polyfunctional compounds in natural and food products; The main components of food - proteins, carbohydrates and lipids - are complex natural substances. These can be multi-functional substances, composite or polymeric compounds; learning to demonstrate the chemical properties of compounds.

Learning outcomes and their assessment

After the course studies the student will have:
in-depth knowledge of the structure and properties of carboxylic acids, hydroxy acids, amino acids, fats, carbohydrates and proteins forming foodstuffs, as well as methods for the determination and purification of organic compounds - lectures and tests;
skills to identify and purify individual organic compounds - laboratory works;
competence - ability to use independently acquired knowledge and skills to explain various processes in relation to organic substances - independent and laboratory work.

14. Summary of lipids, carbohydrates and proteins in food. Test 7 - Amino acids and proteins. Defense of laboratory work protocols (Lecture - 3h, Laboratory work - 2h).

Requirements for awarding credit points

The exam can be taken if:
• developed and defended all laboratory works (50%)
• all tests are successfully written (at least 4 points) (50%).

Description of the organization and tasks of students’ independent work

The students independently prepares for seven tests, solving tasks.
The student independently prepares seven protocols of laboratory work and after the development of the work, they are completed to defend it.

Criteria for Evaluating Learning Outcomes

The exam can be taken when seven tests have been successfully written (at least 4 points) and all laboratory works have been defended. If the average mark of the tests is 8 points and higher, then it is possible for the student to receive the evaluation of the accumulative exam.
