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 ...
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
For example, Δ9-desaturase creates a double bond between the ninth and tenth carbon atom from the carboxyl end. Omega - indicating the double bond is created at a fixed position from the methyl end of a fatty acid chain. For instance, ω3 desaturase creates a double bond between the third and fourth carbon atom from the methyl end.
The proteins are originally oriented in a tangled ball but must be uncoiled into strands; this is referred to as denaturation. There are two ways a protein can be denatured: through physical or chemical process. When forming a meringue the egg whites are beat until the proteins are denatured—a physical process.
Common examples of foods that contain gelatin are gelatin desserts, trifles, aspic, marshmallows, candy corn, and confections such as Peeps, gummy bears, fruit snacks, and jelly babies. [34] Gelatin may be used as a stabilizer , thickener, or texturizer in foods such as yogurt, cream cheese , and margarine ; it is used, as well, in fat-reduced ...
