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.

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.
Chemical denaturation [ edit ] In the less extensive technique of equilibrium unfolding , the fractions of folded and unfolded molecules (denoted as p N {\displaystyle p_{N}} and p U {\displaystyle p_{U}} , respectively) are measured as the solution conditions are gradually changed from those favoring the native state to those favoring the ...
The crusts of most breads, such as this brioche, are golden-brown mostly as a result of the Maillard reaction.. The Maillard reaction (/ m aɪ ˈ j ɑːr / my-YAR; French:) is a chemical reaction between amino acids and reducing sugars to create melanoidins, the compounds that give browned food its distinctive flavor.
Polypeptide chains fold in a particular manner depending on the solution they are in. The fact that all amino acids contain R groups with different properties is the main reason proteins fold. In a hydrophilic environment such as cytosol , the hydrophobic amino acids will concentrate at the core of the protein, while the hydrophilic amino acids ...
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
Human exposure to chemicals, including forever chemicals or PFAS, from food packaging is widespread, according to the study. Experts call it "concerning." Chemicals leaching from food packaging ...
Food physical chemistry is considered to be a branch of Food chemistry [1] [2] concerned with the study of both physical and chemical interactions in foods in terms of physical and chemical principles applied to food systems, as well as the applications of physical/chemical techniques and instrumentation for the study of foods.
