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?
peregrin5@lemm.ee 11 hours ago
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.
Antioxidants have nothing to do with this.
Winter_Oven@piefed.social 10 hours ago
ooh, then I must have gotten the terms wrong...
What I was thinking were the free radicals that are generated during basically most oxygen related reactions in the body, I thought that was called oxidation (at least, in terms of the body).
So, you know anything about how (or if) antioxidants are used against free radicals?

Oxidation is the loss of electrons, whereas reduction is the gain of electrons. The mnemonic is OIL RIG: Oxidation Is Loss, Reduction Is Gain.
Oxygen is highly electronegative (second only to fluorine), meaning that it will strongly pull electrons.
The reason that oxygen is so important for respiration is because of its high electronegativity. It is used as the final electron acceptor in a chain of chemical reactions that are used to convert high energy molecules that you’ve eaten into different high energy molecules that your body can use.
Think of the analogy of a staircase and a ball. The ball is an electron and the stairs are energy states of different molecules along the metabolic pathway. As the ball goes down the stairs, the electron loses energy (which is usually converted to ATP or NADH). At the bottom of the stairs is oxygen, once the electron gets there, it doesn’t have anymore potential energy to lose, unless maybe you have some fluorine around.
An oxygen missing an electron (an oxygen radical) is highly reactive. It’ll just steal an electron from whatever molecule is nearby. That may be DNA or any other molecule that you’d rather keep intact. Antioxidants are helpful as electron donors, neutralizing radicals before they do damage.
This is my understanding, at least. It’s been a while since I took chemistry.

I actually thought about this a few years ago, is it possible that we age because of oxidation to some degree? Is there a way to prevent that? I thought about it, how blood can rust and just had the connecting thought but I’m not smart enough to know if there’s any actual correlation.
Winter_Oven@piefed.social 11 hours ago
Pretty sure oxidation plays a major role in aging, but can't tell you the exact mechanism, I have no idea about it.
But about the blood rust idea, I don't think that can work, cause we don't have just iron particles that can directly interact with oxygen just floating around in our blood, we have a complex (I.e. hemoglobin) that contains significant amounts of iron, which somehow makes it really good for binding to and carrying oxygen.
Deviating a bit, carbon monoxide poisoning is really akin to suffcation iirc, cause it binds and occupies the hemoglobin, effectively reducing the amount of oxygen that can be carried by your blood.
However, do fact check me, I might be wrong about something...

I’m no expert but I’m fairly sure that is basically true in a way. As per zr0’s top-level comment. Forms of life that can make do with less cellular respiration, for example by using external sources to regulate temperature (cold- blooded), don’t need to invite as much oxygen into their cells, and so they get less weird damage over time. Mammals in general have not adopted this strategy.

Statistically speaking, for humans, breathing oxygen does eventually have a 100% fatality rate.

I’ve currently been reducing my oxygen intake. My wife keeps telling me it’s impossible and my doc says I’ll supposedly die, but they’re just hating on my progress.

To sum up - because I taught this to a kid yesterday - for a period, life photosynthesized and oxygen was toxic to most living things. There were large growths of photosynthetic Cyanobacteria that pumped the air full of oxygen. Living things at the time (like, bacteria and microbes, nowhere near vertebrates) couldn’t handle all the O2 and died.
