Are proteins sensitive to change in pH and temperature?

WebThe influence of pH on protein-protein interactions in solution works through altering of the electrostatic properties of protein surfaces. At pH equal to the protein's isoelectric point (pI), where its net charge is neutral, charge repulsions of similar molecules are relatively low and many proteins will aggregate. WebJan 20, 2024 · It is important to remember that protein shape is sensitive to pH, temperature and dissolved salts. By changing these variables the activity or function of the protein will be altered. If the protein’s shape is altered so severely that the protein no longer functions, the protein is said to be denatured.
