That sounds good. What would they not digest then?

Should we figure out how they might synthesize it?

probably not the compounds that are found in the prey but not the predators, such as the pigments used for photosynthesis.

I think that the only really important part is the thiol group.

Which part is that? I can see the SH part, but I don't know what other part of the molecule belongs in the thiol group.

SH is the complete thiol group.

Oh, ok. When I looked up thiol it showed a radical group connected to it. Do we need to figure out how the thiol group is synthesised or not?

It has to be attached to some larger molecule at a carbon atom, but the actual group only consists of one sulfur atom and one hydrogen atom.

I wouldn't be concerned about it.

Yes, I realized that.

Good. So predators use glutathione to neutralize reactive oxygen species. What might prey do in response?

The prey would probably excrete more reactive oxygen species, evolve movement capabilities, and evolve some sort of defensive spike proteins.

The spike proteins would especially discourage engulfing. The predators might secrete some acid or some other corrosive substance to disintegrate them.

But how would that not harm the predator equally?

They could eject a vesicle, but maybe it would be hard to synthesize it in the first place.

Yes, and it would be difficult to target.

Ok, let's scrap that idea. What would predators do then (if anything)?

They could excrete sulfuric acid in order to denature the spike proteins.

Isn't that basically the same thing?

Yes, but I had previously forgotten that those creatures will probably have gotten used to acidity earlier.

Ok, good. Would they secrete it with vesicles or vacuoles or somwthing else? I also think this is enough adapting for now.

They would likely excrete it via vesicles.
Actually, would the creatures be used to sulfuric acid? They would have a lot of sulfate (and, to a lesser extent sulfite), but if they aren't electrically charged, then there would have to be a bunch of every hydrons as well.

What are "creates"?

How does sulfuric acid form naturally? Also, there is a substantial amount of isocyanic acid, but it wouldn't be nearly as acidic.

The creatures oxidize sulfur dioxide.

With the arrival of oxygen then there might be a slight increase in the amount of sulfuric acid (but not much because oxygen there wouldn't be too much that deep down).

Yes, but they already had another method.
