  4. (denatured) changed in nature or natural quality; "denatured alcohol"
  5. (Denaturation (fissile materials)) Denaturation of fissile materials suitable for nuclear weapons is the process of transforming them into a form that is not suitable for weapons use and can not easily be reversely transformed. ...
  6. (Denaturation (food)) Food is deliberately "denatured" when it is rendered inedible via the use of chemical and/or physical adulterants, which are intended to affect the food's palatability or appearance to a degree whereupon it becomes unappealing or even toxic to consume.
  7. (Denaturation (protein)) Denaturation is a process in which proteins or nucleic acids lose their tertiary structure and secondary structure by application of some external stress or compound, such as a strong acid or base, a concentrated inorganic salt, an organic solvent (e.g. ...
  8. to take away a natural characteristic or inherent property of a thing or a person; to add something that makes alcohol unsuitable for consumption but leaves the alcohol suitable for other purposes; To subject (especially a protein) to conditions altering its original form or state; To combine ...
  9. (denatured) Having been deprived of its nature, having had its nature changed; Of alcohol made undrinkable, by adding a toxin or unpalatable substance, but still useful as a fuel or solvent. Traditionally by the addition of methanol (wood alcohol)
  10. (Denatured) Ethanol that has had a substance added to make it unfit for human consumption.
  11. (Denatured) A spirit to which a substance is added to render it unsuitable for consumption, with the aim in mind to avoid the heavy taxes which are imposed.
  12. (Denatured) Conformational change in an antigen that may help expose an epitope to the antibody, or destroy an epitope.
  13. (Denatured) Loss of the natural extractives from the timber surface through exposure to sunlight and rain, resulting in greying and bleaching of timbers.
  14. (Denatured) Term describing alcohol which is unfit for consumption due to modification by heating. Used in mold making and casting.
  15. (Denatured) The act of making meat or left overs from being fit for human consumption. Usually be treated with chemicals, some times deadly chemicals so that meat cannot be used for human consumption.
  16. (denatured) A change in a protein molecule, usually by unfolding of the amino acid chains, with a decrease in solubility.
  17. (Denaturation) The process of making double-stranded DNA single stranded.

  19. Denaturation is the loss of the native configuration of the macromolecule, such as the unfolding of the tertiary structure of an antibody protein. Denaturation usually results in the loss of the macromolecule's biological or immunological reactivity or solubility.
  20. (Denaturation) The physical changes that occur in proteins when secondary and tertiary structures are disrupted. Denaturation is usually brought about by heat treatmetnt or by a change in pH and is accompanied by a loss of biological activity.
