The core principle of protein denaturation by temperature is the disruption of non-covalent intramolecular forces, such as hydrogen bonds, hydrophobic interactions, and ionic bonds, which maintain a protein's tertiary and secondary structure. This mechanism relies on the formal definition of denaturation as the irreversible or reversible loss of native three-dimensional conformation without breaking the primary peptide bond sequence. Within the domain of biochemistry and structural biology, this concept represents the thermodynamic transition from a folded, functional state to a disordered, inactive state driven by thermal energy exceeding the stability of weak interactions.
