Here's a sort-of transcript for the copper section
There's the copper-zinc-SOD in the cell (there's also an SOD outside the cell, which is also copper dependent; and an Mn SOD). SOD, catylase and glutathione are part of the body's defence against oxidative stress (which we could call rust). Copper is essential for SOD and it's needed for catylase (which needs iron, but iron is only as good as the copper) and glutathione peroxidase (needs Selenium and magnesium, but doesn't work as well in a copper deficient body). Copper is, in fact, the workhorse that prevents rust in the body.
So what about zinc and kryptopyrroles? ... some discussion about chemistry (minute 48.5).
Haemogloblin is 4 pyrroles with iron at the centre. This makes haem an important chemical, allowing iron to store oxygen in the body. But, the enzymes that get the iron where it should be work only in the presence of copper (min 50).
The issue with copper in this context is faulty haem production. While the pyrrole does cause issues with loss of zinc and b6, it's because copper is not available to make the haemoglobin, zinc and b6 are destroyed in the body.
This means we are treating a symptom of low zinc and b6, when, in fact, it is a copper deficiency that's causing the problem and never gets addressed.
[discussion of sugars in alcohol] ... when people are short of copper, they're going to crave sugar to help build dopamine. Drinking gets rid of the magnesium, zinc, b6. When the liver can't function any more, it stops making ceruloplasm, and then the alcohol craving continue ... [looking for sugar/alcohol to boost dopamine]
