Aspirin can also play around with this. Where? The same kind of uncoupling agent. This can lead to a metabolic acidosis. Because it releases the hydrogen ions into the cytopazen. And so, that then is part of the reason for, I always thought metabolic acidosis from aspirin was due to, because it is an acid. But it's actually partly because of this process. Also hibernating animals and babies produce this in their brown fat. Or is this the thermogenic process of brown fat? Yes. Is it really? Yeah. Oh, how cool? I don't know. All right.
