basic academic studies

Study program:

Biochemistry: 2. year, winter semester, compulsory course

Teachers:

Dragomir R. Stanisavljev, Ph.D.
full professor, Faculty for Physical Chemistry, Studentski trg 12-16, Beograd

Nemanja M. Gavrilov
associate professor, Faculty for Physical Chemistry, Studentski trg 12-16, Beograd

Assistant:

Maja M. Rankoviæ

Hours of instruction:

Weekly: four hours of lectures + three hours of labwork (4+0+3)

Goals:

The main goal of this course is to help biochemistry students acquire the essential general knowledge in the field, which should help them understand some of the courses in the later years of their studies. It introduces students to the basic physicochemical concepts and the determination of important variables.

Outcome:

Students will learn to thermodynamically describe and analyze systems in the conditions of the chemical equilibrium. They will become familiar with the basic irreversible processes, such as viscous processes, diffusion, sedimentation and electrophoresis. Students should be able to understand the atomic structure of matter and analyze time changes of systems.

Teaching methods:

Lectures, laboratory exercises.
