Please describe the process by which a prion is rendered harmless at a mere 100C. Denaturing a protein generally requires a lot more.

- SideburnsOfDoom 9y ago> Denaturing a protein generally requires a lot more .. than 100C Nope. Protein generally denatures at lower than 100C / boiling point. That's the principle of Sous Vide, not that you should use Sous Vide to sterilise anything, but the protein in egg white denatures at 60-80C. http://www.scienceofcooking.com/eggs/eggs_sous_vide.htm http://www.scienceofcooking.com/eggs/eggs_sous_vide.htm And in meat it's similar, 50-70C http://www.mpip-mainz.mpg.de/Sous_vide_cooking http://www.mpip-mainz.mpg.de/Sous_vide_cooking If you doubt it, stick your hand in water at 80C and see what happens.
- aaronblohowiak 9y agoPrions don't degrade at the boiling point: http://www.microbiologyresearch.org/docserver/fulltext/jgv/82/2/0820465a.pdf?expires=1518047129&id=id&accname=guest&checksum=5B41A4F4F072CF1011FBADABD6ED4C6E http://www.microbiologyresearch.org/docserver/fulltext/jgv/8...
- SideburnsOfDoom 9y agoSure, though that's entirely different from the grandparent post's statement about "Denaturing a protein generally", which happens well below boiling point.
- jjoonathan 9y agoWhere did I claim they were rendered harmless at a mere 100C?
