Copper was labelled a toxic hevy metal in error. It is a necessary nutrient. When a protein is missing a copper ion where it's supposed to be, it's prone to collapse, causing amyloid diseases like alzheimers. (this is also the reason why copper bowls is needed for good quality whipped eggs, since it fills up the missing copper sites) See the amounts used in animal feeds, human medicine got the numbers almost certainly wrong. The difference is so massive the EU restricted the concentrations to 150mg/kg feed, since the amounts used were deemed toxic to the environment.

I've read that the lack of the enzyme choline acetyl transferase might be a cause. What about that?

>> No.11217200

>>11217065
That may only be a consequence. Many enzymes do need copper to function, but as far as I know, choline acetyltransferase is not among them.

yeah, i know there is a meme floating around that dementia is separate from aging but i think the model where we consider cancer, alzheimers, etc a normal part of aging makes more sense given the prevalence, development ages, and mechanism. it's not like infection. this is the body running it's "natural course".

It seems to be a common myth that started to appear what I could found maybe 50 years ago. In the western medicine at least. There are even laws regulating it and it's hard to get cookware that isn't lined, unless it's for purely decorative purpose. But as far as I know, it was common to even make jams in copper pans. I in fact couldn't find where the myth came from, it seems to be a complete mystery, it seems it just appeared out of nowhere.

copper toxicity is not a "meme", it is well-described at higher doses and it is severe. low doses are the issue. But any skeptical person should keep in mind that we used cookware and plumbing and even FOOD made with lead for centuries before its toxicity was understood. Similar case with mercury. These sorts of poisons can be very statistically subtle because the required exposure is typically long-term. All the more so with copper where people appear to have developed an immunity to low doses -- though if we don't even understand this mechanism, how could we pretend to understand its flaws?

>> No.11220290

>>11220228
But copper is used in much higher doses in animal feeds. Not only it isn't toxic, it has beneficial effects. It almost appears as if there was a decimal point error in the human RDI. In any case it doesn't seem there were any notable human poisoning cases either. The dangerous effects of lead were known since the antiquity.

there aren't "missing" copper sites, in fact the copper is interfering with normal protein function. the copper blocks disulfide bonds from forming

>> No.11222798

isn't it the copper salts that are the real problem?

>> No.11224486

>>11222797
There are places in the protein that require copper to hold them together, otherwise the protein isn't stable. (other metals can bind to those sites as well, but they won't make the protein more stable) It doesn't block the protein function, it prevents its collapse and denaturation. And the same creates amyloid plaques, the proteins are easily disturbed when they are missing their respective metal.

Copper IS toxic in excess, a lot of beneficial elements are toxic when there's too much of it in the body.
