Oxidation is how red blood cells collect oxygen to pass to the rest of the body. In fact it is iron in hemoglobin that "rusts" to collect the oxygen. You would die if your blood didn't "rust".
Antioxidants have nothing to do with this.
The process you’re thinking of is oxygenation, not oxidation. Oxygenation is the binding of oxygen to other molecules, oxidation is the loss of electrons. When the iron in hemoglobin oxidizes (from Fe2+ to Fe3+) it stops binding with oxygen, and if it oxidizes further (to Fe4+) it can start oxidizing other molecules in your body. Your body has enzymes to reduce the iron back to a reactive state, but antioxidants also play a role in reducing oxidized molecules.

It's actually the opposite. When the oxygen binds to the iron it changes from Fe+2 to Fe+3 so the binding of oxygen to the iron in hemoglobin is an oxidation process. At that point it can't take more oxygen until it releases it in a reduction reaction.
The term "oxidation" is originally derived from reactions where a substance combines with oxygen but has since been generalized to any reaction where an electron is given up. So "oxidation" is the broader term and "oxygenation" is the specific oxidation reaction that results in binding oxygen.

Wait until you read about Dihydrogen Monoxide. Everyone who has ever been exposed to it has died.

Delicious fluorine for me please
I've been thinking about neon. Imagine breathing out multicolour bright lights!

There's a whole website dedicated to raising awareness of its danger : https://www.dhmo.org/

Our lives are a balance between needing oxygen and preventing oxidation damage. We have several enzymes that constantly reduce radicals and chemicals caused by oxidation. So yes oxygen is continuously damaging us. And will eventually win.

Oxygen will burn your lungs, that’s why we dilute it with nitrogen

I mean, oxygen is the most aggressive oxidator, to the point we named the process after it.
F you.

Pure oxygen is actually toxic for humans, leading to hyperoxia. People who breath pure oxygen such as scuba divers need specific training.

There are quite a few sci-fi stories and short stories built on a similar concept. One of my favorites is an alien ship lands on a random farm in the US and (leaving a lot of details out, read the book!) it comes to light that the aliens normally live at insanely hot temperatures like 900F (480C) and consider Earth an "Ice World" (that's also the name of the book). Anyway, one of the catches in the book is that farmer figures out the alien wants to trade (again skipping a lot of details) but all he has on him that he can give up is a cigarette (the farmer doesn't know it's super hot inside the ship). He does the trade and we later find out that most of the galaxy is INSANELY vulnerable to being 100% completely utterly addicted to nicotine. When the alien took in the cigarette it instantly vaporized and sent the nicotine into the air and they breathed it and became instantly addicted worse than any opiod addiction IRL.
You didn’t mention the book name, so how are we to read it?

Wel, every single human who breathes Oxygen dies eventually. Just saying.

On the topic, as oxidation is a pretty prevalent negative side effect of living, our body has multiple mechanisms to deal with it, no? So my question is: where do the "antioxidants" that we can eat come into the picture here? Are they like preventing oxidation from even occurring, or are they like the shields that our cells use to protect themselves from oxidative stress, or what have you?
wrote on last edited by [email protected]we have enzymes to prevent oxygen radicals from forming. such as Superoxide dismutase, which is present in nearly every cell in our body, and we have 3 different version. most oxygen dependant organisms have similar enzymes.
another fun fact, our immune system can produce the same superoxide as a defense against bacterial infections, reactive oxygen species including radical oxygen. but bacteria can produce the enzyme to neutralize that too.
i think the dietary source, is somewhat alittle homeopathic/ pseudosciency, because our stomach acid would probably neutralize any beneficial effect before we can absorb it. of course there are some foods that provide nutrional benefit to certain cells(if they a chemical compound). but they dont have like anti-oxidant effect of something like superoxide dismutase. also because of this effect, people with chronic illness as a result of the dysfunction.

So to not die, we just need to stop breathing !
