The mirror, it's literally a mirror image.

A mirror image, yeah.

So for example, allulose is an enantiomer of fructose.

Yeah.

If you draw fructose and you hold it in the mirror, what you see is not fructose.

It's the reflection of fructose, but that's allulose.

Oh, it's not?

I always thought it was an enantiomer.

It has another flip.

Oh, okay.

So it's two flips.

But why does this matter chemically?

I think the point I want to make to people is when you have a D and an L of something, do they behave the same?

And is that just because it sticks around longer and therefore crosses the blood-brain barrier or in the case of the brain?

Right.

But if you just take the total metabolism of it, are you saying one mole of one and one mole of the other produce a different amount of ATP?

This is when you were saying that Veach's initial compound was your first attempt and it didn't work.

What do you make of the fact that there hasn't been any efficacy of NAD supplementation or even NAD precursors?

NR and NMN have really not yielded any meaningful or measurable benefits.

The only thing I've ever seen that looked somewhat positive was in the trial that looked at patients with ALS.
