| HN Mirror

The technical term is "parity simetry" https://en.wikipedia.org/wiki/Parity_(physics) that means that a system and the mirrored version behave exactly in the same way.

Chemistry is about electromagnetism, and electromagnetism has parity symmetry. Also gravity is somewhat important, but gravity also has parity symmetry. And even the strong force has parity symmetry. So for all practical purpuses, chemistry has parity symmetry and when you mirror a bunch of molecules, the mirrored versions will behave exacly as the normal ones.

But ... if you were looking carefuly I didn't mention the weak force, because it breaks the parity symmetry. It's very difficult to prove it https://en.wikipedia.org/wiki/Wu_experiment You have to get a bunch of radioactive cobalts, put them in a strong magnetic field, keep them super cold, and you will get 60% of the decays in one direction and 40% in the other, breaking the 50% and 50% expectation if it didn't break the parity symmetry.

Can this experiment be reproduced in a chemistry molecule?????

I need more questions marks ????????

I think no one has done it and it looks very difficult to try. Can I use my imagination and make will guess?

Let's say you get something like the hemo part of hemoglobin https://en.wikipedia.org/wiki/Heme It has four nice nitrogens that probably can bind to cobalt instead, or perhaps you need a variant. Now make some substitutions to break the symmetry so it it's like a recycle symbol that has a clear direction. Add some bridge under the plane, perhaps connect the small part that is bellow the graphic that I'm not sure why iis useful.

And make the mirrored version too.

Now, if the design was super smart, most of the cobalts in a version will have the north pole pointing to the bridge, and the mirrored version will have the south pole. I'm not sure it's possible, but I can handwave some explanation that say it's possible, but perhaps this idea makes no sense.

Now, did I mention you need radioactive cobalt? When it desintegrates it send an electron that will sometimes colide with the bridge and destroy it, or go in the other direction and keep the molecule without changes.

So after some time the you can see that the time to self destruction is different in the original and the mirrored version.

In conclussion, I think it's possible but no one has done it, no sane person would try it, and if someone get it working then they will get a Nobel price.

It will be very expensive, and completely unuseful, so I completely not expect to see something like this is a living cell.
