ATPase copper transporting beta

But that enzyme gets activated by a derivative of retinol, by a derivative of vitamin A.

And that's called ATP7B.

And it's a sister enzyme called ATP7A that loads all the other copper enzymes.

Again, the key is retinol.

And so looking at copper, ceruloplasmin, we're looking at zinc, we're looking at vitamin A and vitamin D, not just D, you got to look at A.

And the reason why A is important is the copper pumps, ATP7A and ATP7B, which I'm sure given the work that you do, you're familiar with those markers, but they're activated by retinol.

You can't start those pumps

without,
