SUMMARY
Changes in pH significantly affect tertiary protein structures by disrupting ionic bonds, which are crucial for maintaining their three-dimensional conformation. Urea, a denaturant, breaks all bonds except covalent bonds, leaving the primary structure intact while altering higher-order structures. The discussion emphasizes that tertiary proteins are sensitive to pH variations due to their reliance on ionic interactions. Understanding these concepts is essential for studying protein stability and functionality.
