In actual fact, you are more likely to have complications from NOT boiling and denaturing your protiens. Most cellular organisms have at least some form of protease, that could attack your desired yeast if left active in solution, and also Im pretty sure that yeast are high enough organims to have a simplistic defence mechanism, which is most likely a DNA polymerase, and that will screw things around. (although you could get a cool recombination event with bits of DNA from different parts of the chromosome, and from different species ... teenage mutant nija yeast).
Danzar, dont forget that under a Substituition nucleophillic reaction mechanism you are likely to undergo a 1,2-hydride or methyl shift, that can tautomerise your chiral centre. PS dont try translate that, its not actually scientifically sound, although statistically the mean of life is 42.

My sentiments exactly , I have NFI.Danzar wrote:Jesus Christ.111222333 wrote:Regarding the denaturing of proteins, I wouldn't have thought that the yeast is able to transport the entire peptide across the lipid bilayer without digesting it first (ie could be in a vesicle, but not get in to the cytosol), I mean after all even we can't do that, at least not without having an active transporter for that specific protein, so denaturing it first wont have much impact.
Well, if you take an asymptotic line and extend it outwards, you'll create a transfusion of the asymptotic line and airborne particles that will, in fact, shift their bipolar structure, thereby creating tension amongst rabbits (of which there are many). We all know what rabbits do to relieve tension, so, with the ensuing rabbit plague, poor nations will become well fed and rich nations will spend all of their money eliminating rabbits with lupile pesticides, which will, in fact, create an army of clone rabbit/human hybrids that will go to war against the suddenly well-fed poor nations, creating a rift in the space time continuim that will destroy the universe (unless Arnie gets to the Church on time).
Just kidding - I really do need to get myself a little more up-to-speed on some of the more scientific elements of brewing. I am impressed.
Danzar, you left out the Great Wall Of China that actually kept out the rabbits.
One simple question, is it "Good" to boil the yeast, without getting too technical....Just think of me as Homer Simpson when I ask this question.

Once the yeast is dead, it doesn't really matter whether you boil or not. Things "could" go wrong if some enzymes aren't denatured, but its very slim chance, but it wont matter in the slightest if you denature the enzymes. As i said you are more likely to have complications from not denaturing the proteins, but this is still tiny.

In future, when someone suggests you throw old packets of yeast into a boil to use the nutrients, just smile and nod. Do not ask questions. Do not ask for clarification. Just smile and nod.
Smile ... and nod.
Unless someone can reasonably substantiate why we shouldn't.

Now I`m all mixed up again . Do you mean why we shouldn`t smile and nod? Or why we shouldn`t throw old packets of yeast into the boil?chris. wrote:Totally....SpillsMostOfIt wrote:Now, let this be a lesson to you all.

I`ll stop smiling and nodding till there`s a clarification, just to be on the safe side.
