Biochemistry is a science concerning the chemical reactions occurring in living cells and organisms.
Biochemistry in the medicine is mainly concerned with balance of biochemical reactions occurring
in the body, both in physiological state as in pathology.
The program of teaching biochemistry for medical students consists of lectures, laboratory classes,
tests, presentations.
The purpose of teaching "Biochemistry" in the direction of Medicine is to deepen the knowledge
of the chemical processes occurring in the surrounding world. Understanding the importance of
chemistry in biological and medical sciences to the extent necessary for further medical studies.
The aim is also to prepare students for teaching clinical subjects, as well as to work in the
profession. Allow you to see the contents transferred to pathological changes in the structure and
functioning of the most important biomolecules (proteins, nucleic acids, carbohydrates, lipids),
allow you to understand the basic pathways of catabolic and anabolic explain the mechanisms of
metabolic diseases.
