In biochemistry, denaturation is a process in which proteins or nucleic acids lose folded structure present in their native state due to various factors, including application of some external stress or compound, such as a strong acid or base, a concentrated inorganic salt, an organic solvent (e.g., alcohol or chloroform), agitation and radiation, or heat. [3]
Denaturation is the process by which foods or liquids are made unpleasant or dangerous to consume; it is done by adding a substance known as a denaturant. Aversive agents —primarily bitterants and pungent agents —are often used to produce an unpleasant flavor.

Visual representation of protein denaturation. A globular protein becomes unfolded when exposed to heat. Aerated egg whites are frequently employed in shaken cocktail recipes, such as this Ramos gin fizz, for textural and aesthetic purposes. The physical stress of beating egg whites can create a foam. Two types of physical stress are caused by ...
Many allergies are caused by the incorrect folding of some proteins because the immune system does not produce the antibodies for certain protein structures. [5] Denaturation of proteins is a process of transition from a folded to an unfolded state. It happens in cooking, burns, proteinopathies, and other contexts. Residual structure present ...
Denaturation (biochemistry), a structural change in macromolecules caused by extreme conditions; Denaturation (fissile materials), transforming fissile materials so that they cannot be used in nuclear weapons; Denaturation (food), intentional adulteration of food or drink rendering it unfit for consumption while remaining suitable for other uses
Using the above principles, equations that relate a global protein signal, corresponding to the folding states in equilibrium, and the variable value of a denaturing agent, either temperature or a chemical molecule, have been derived for homomeric and heteromeric proteins, from monomers to trimers and potentially tetramers.
