[biochemistry] Note 1: Modified from the definition given in ref. Note 2: Denaturation can occur when proteins and nucleic acids are subjected to elevated temperature or to extremes of pH, or to nonphysiological concentrations of salt, organic solvents, urea, or other chemical agents. Note 3: An enzyme loses its catalytic activity when it i...

[fissile materials] The situation with Uranium-233 is more drastic. Decay of the attached Uranium-232 produces Thorium-228 with a radioactive half-life of 1.9 years and several short-lived daughter nuclides; these daughters include some very hard gamma-ray emitters like Thallium-208 and Lead-212. After approximately one single year the alph...

[food] Food or drink is deliberately denatured when a substance known as a denaturant is added to render the food unpleasant or dangerous to consume. Aversive agents—primarily bitterants and pungent agents—are used to produce an unpleasant flavor. For example, the bitterant denatonium might be added to food used in a laboratory, where s...
