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.
