  2. Denaturation (food) - Wikipedia

    en.wikipedia.org/wiki/Denaturation_(food)

    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. For example, methanol is blended with ethanol to produce denatured alcohol.

  3. Denaturation (biochemistry) - Wikipedia

    en.wikipedia.org/wiki/Denaturation_(biochemistry)

    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.

  5. Gel electrophoresis - Wikipedia

    en.wikipedia.org/wiki/Gel_electrophoresis

    Nucleic acids are often denatured by including urea in the buffer, while proteins are denatured using sodium dodecyl sulfate, usually as part of the SDS-PAGE process. For full denaturation of proteins, it is also necessary to reduce the covalent disulfide bonds that stabilize their tertiary and quaternary structure , a method called reducing PAGE.

  6. Denaturation - Wikipedia

    en.wikipedia.org/wiki/Denaturation

    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

  7. Globular protein - Wikipedia

    en.wikipedia.org/wiki/Globular_protein

    Even in the protein's denatured state, it can be folded into the correct structure. Globular proteins seem to have two mechanisms for protein folding, either the diffusion-collision model or nucleation condensation model, although recent findings have shown globular proteins, such as PTP-BL PDZ2, that fold with characteristic features of both ...

  8. Denaturation mapping - Wikipedia

    en.wikipedia.org/wiki/Denaturation_mapping

    When subjected to denaturing factors like increased heat or chemicals like formamide in low levels, DNA is partially denatured in a predictable pattern based on its nucleotide content in different regions. [1] This allows unique fingerprints or ‘barcodes' to be generated for molecules with different sequences not unlike restriction mapping.

  9. Biological value - Wikipedia

    en.wikipedia.org/wiki/Biological_value

    Biological value (BV) is a measure of the proportion of absorbed protein from a food which becomes incorporated into the proteins of the organism's body. It captures how readily the digested protein can be used in protein synthesis in the cells of the organism. Proteins are the major source of nitrogen in food. BV assumes protein is the only ...
