The goal | The main goal is to enable students to use biochemical methods for identification and quantitative determination the most important natural compounds, which are prerequisite for following the course of biochemical processes. Methods for determination of protein concentration, protein purification, and enzyme activity assays will be learned and subsequently applied in microbial enzyme production and determination of kinetic constants. | |||
The outcome | Students will become skilled at techniques and methods used in biochemical laboratory. During the course students gain basic knowledge on extraction of bioactive cell compounds (vitamins and proteins) and their further purification, determination and characterization. Moreover, students will be learned to process, analyze and present experimental data. | |||
