Laboratory work #1: «Effect of Various Conditions (Temperature, pH) on Protein Structure»
Description: In this lab work, students investigate the effect of external factors — temperature and pH — on protein structure. Egg white is used as an example, as it contains the protein albumin, which is sensitive to changes in the environment.
During the experiment, students observe the process of protein denaturation under the influence of acid, base, and heat.
