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.

A bitterant (or bittering agent) is a chemical that is added to a product to make it smell or taste bitter. Bitterants are commonly used as aversive agents to discourage the inhalation or ingestion of toxic substances.
SDS is a strong detergent agent used to denature native proteins to unfolded, individual polypeptides. When a protein mixture is heated to 100 °C in presence of SDS, the detergent wraps around the polypeptide backbone. In this process, the intrinsic charges of polypeptides becomes negligible when compared to the negative charges contributed by ...
Similarly, RNA and single-stranded DNA can be run and visualised by PAGE gels containing denaturing agents such as urea. PAGE gels are widely used in techniques such as DNA foot printing, EMSA and other DNA-protein interaction techniques. The measurement and analysis are mostly done with a specialized gel analysis software.
An alternative source of free radicals is riboflavin, which generated free radicals in a photochemical reaction. TEMED (N, N, N′, N′-tetramethylethylenediamine) (C 6 H 16 N 2; mW: 116.21) stabilizes free radicals and improves polymerization. The rate of polymerisation and the properties of the resulting gel depend on the concentrations of ...
Aversive agents—primarily bitterants and pungent agents—are often used to produce an unpleasant flavor. For example, the bitterant denatonium might be added to food used in a laboratory, where such food is not intended for human consumption. [1] A poisonous substance may be added as an even more powerful deterrent.
Asbestos kitchen tiles turned to dust, cars burned to their frames. The lack of rain this winter played a significant role in allowing the Palisades Fire to grow so big, so fast.
Denaturation may refer to: . 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
