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.

The Unit Identification Code (UIC) is a six character alphanumeric code that uniquely identifies each United States Department of Defense entity. The UIC is often used on various paperwork to assign a soldier to a specific company in which they fall under. The first character is the Service Designator: [1] A: US Department of Agriculture
In the less extensive technique of equilibrium unfolding, the fractions of folded and unfolded molecules (denoted as and , respectively) are measured as the solution conditions are gradually changed from those favoring the native state to those favoring the unfolded state, e.g., by adding a denaturant such as guanidinium hydrochloride or urea.
The most famous example is the hyperchromicity of DNA that occurs when the DNA duplex is denatured. [1] The UV absorption is increased when the two single DNA strands are being separated, either by heat or by addition of denaturant or by increasing the pH level. The opposite, a decrease of absorbance is called hypochromicity.
English: Process of Denaturation: 1) Functional protein showing a quaternary structure 2) when heat is applied it alters the intramolecular bonds of the protein 3) unfolding of the polypeptides (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
On the other hand, for fast-folding proteins (i.e., those with a relaxation rate of 1 to 100 microseconds), pressure jump (dead time~few microseconds), [1] temperature jump (T-jump; dead time~few nanoseconds) or continuous flow mixing (dead time~few microseconds), [2] can be carried out at different denaturant concentrations to obtain a chevron ...
[2] The method is named after the British biologist Edwin Southern , who first published it in 1975. [ 3 ] Other blotting methods (i.e., western blot , [ 4 ] northern blot , eastern blot , southwestern blot ) that employ similar principles, but using RNA or protein, have later been named for compass directions as a sort of pun from Southern's name.
