OH!

Some of what looks like water is actually "OH" not H₂O, and this hydroxyl can be a real "OH-OH."

The link you gave mentioned:

But it was unclear whether that hydrogen was in the form of hydroxyl – the chemical that makes up drain cleaners – or in the form of H2O, or water.

The NIH.gov site cites a biochemical journal about hydrogen peroxide (HOOH), which adds this:

. . . to generate hydroxyl radicals (OH.) from H2O2 has been investigated . . .

And all this, of course, was presented, just as a setup for the old H₂O₂ joke:
