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

hyper - meaning high,

ox - meaning the animal Ox,

-ia - meaning presence in blood.

High Ox presence in blood. You can imagine how dangerous that is.

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

Wait till you hear about this ancient roman curse called gravity.

F you.

Unrelated but the bottom navbar in that screenshot makes me long for the Alien Blue days of Reddit. I also just miss that iOS design (along with the OS X Mavericks design)

I got my oxygen intake down to single digits! My family wasn’t supportive however and got me a new pair of lungs, haters

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.

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 attract electrons. So, oxygen is good at oxidizing things. It's good at stealing their electrons. (When the oxygen takes the electron, the oxygen becomes reduced!)

The reason that oxygen is so important in your body 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. The final, reduced state of oxygen in this pathway is carbon dioxide. It's no longer useful for respiration and thankfully can just be exhaled. How convenient!

An oxygen missing an electron (an oxygen radical) is highly reactive. This is not good. It'll just steal an electron from whatever molecule is nearby. That may be DNA or any other molecule that it's in your best interest to keep intact. Antioxidants are helpful as electron donors, neutralizing radicals before they do damage.

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.

Cell mechanisms cause oxidative stress in the body which can lead to inflammation and faster aging. Antioxidants provide the body with an easy way to neutralise the bi-products.

Did you know that dihydrogen monoxide kills more people than any other liquid? And yet, the government does nothing to ban it. This deadly liquid could be anywhere, even in your home!
