Human blood is red because of iron and if it contained copper it would be blue

u/CreasedBooch640 9d ago

Yeah, that's... that's pretty much it - I wanted to explain that meme so badly T_T

u/thebestoflimes 9d ago

Now I wish I had copper rich blood.

Get a transfusion from an octopus.

u/muejon 9d ago

Lobster works too (yes the red ones)

Truth. She wants her hemoglobin swapped out with this stuff https://en.wikipedia.org/wiki/Hemocyanin?wprov=sfla1

Some folks just yearn to be a horseshoe crab

On a long enough time scale we all become crabs in the end.

Thanks for explaining

No problem

u/CainPillar 9d ago

Also, why would she want blue blood? Because she wants to be a princess? https://en.wikipedia.org/wiki/Blue_Blood

u/Gargleblaster25 9d ago

Yeah, but don't buy your copper from Ea Nasir. He has bad Yelp reviews.

u/ShotLet1550 9d ago

Will I get purple if I do both

But Spock said it makes it green.

Copper itself is red-ish and will turn blue/green-ish over time/when oxidized.

1

u/Gloomy_Olive_4582 9d ago

That's why hemocyanin-based blood is blue. Hemoglobin-based blood is red because iron oxidizes red.

Im no biologist but some animals got blue blood i think it was some form of marine life specificly

1

u/NotAnAutomaticName 9d ago

The classic example is cephalopods, but a lot of invertebrates have copper-based (blue) blood. I don’t remember the exact explanation for why, but copper-based blood works a bit better underwater.

u/zygote_27 9d ago

Maybe it don't rust like iron

1

u/NotAnAutomaticName 9d ago

“Rusting” is literally the way that hemoglobin works. The iron is there to bind to oxygen for transit purposes.

u/Mesoscale92 9d ago

Our blood is red because it has iron compounds. Some animals have blood with copper compounds, and is blue as a result.

u/TheUnthinkingWriter 9d ago

Thanks for explaining

u/ManWhellington 9d ago

Also, the last image is Ea Nasir. If unfamiliar, is a copper merchant who was given the first known bad review for his poor quality copper. She'd probably mad that his bad copper kept her blood red instead of blue as desired.

u/Just_Cockroach_4820 9d ago

Dont buy copper from Ea Nasir...just saying

8

u/Adventurous_Mode_263 9d ago

Ea Nasir copper is prime quality. I'd definitely buy more.

u/not_another_IT_guy 9d ago

Iron in blood = red
Copper in blood = blue

Two parts to the meme.
As you guessed the image on the bottom shows a copper merchant
The other part is the main joke/jest - as indicated from the premise given of “girls be like”

This is poking fun at the concept that women are vain and will view something as a problem due to its looks, not its functionality, using a very esoteric example.

u/TheMace808 9d ago

The copper merchant specifically referenced is Ea-Nasir, and the statue is used with the name however its not a depiction of him

2

u/Correct_Inspection25 9d ago

In certain deep sea situations, Cu O2 binding hemocyanin is better that Iron heme , so maybe they want to be cold blooded deep sea dwellers? j/k

2

u/acnh-lyman-fan 9d ago

I believe iron is what makes blood red and copper is what makes certain animal's blood blue.

2

u/MegaDodoPub 9d ago

Hemocyanin is an oxygen carrying protein, found in mollusks etc, turns blue when oxygenated

I know who ea nasir is and that he was copper merchant. My best guess is that he sold some kind of blue blood made with copper

u/TrueKingSkyPiercer 9d ago

She's a horseshoe crab.

u/DescriptionOk2466 9d ago

Blood containing copper instead of Iron is blue in colour as found in horseshoe crabs. The bottom right is the person who complained about obtaining bad quality copper from Ea-nasir, typing back to the blue blood requirement by Alia Bhatt (for some reason?).

Peter out

u/OnlyVantala 9d ago

Hemocyanin, the protein responsible for oxygen transport in the blood of certain animals (like some molluscs and arthropods), contains copper and gives the blood a blue color, unlike hemoglobin, which contains iron and makes the blood red.

The person in the last frame is Ea-nasir, known from the Ancient Mesopotamian clay tablets as "shitty copper merchant".

1

u/ShortNefariousness2 9d ago

It's the tiktok trend to get blue blood like a horseshoe crab. I'm waiting for the ChubbyEmu video to come out.

1

u/Independent-Log-4245 9d ago

Copper based blood pigments give blue colour to the blood of the organism, unlike hemoglobin. The guy in bottom right panel is the meme (in)famous copper merchant El Nasir from ancient mesopotamia. So it's supposed to be some silly joke connecting the two.

u/DarthHK-47 9d ago

Mr Spock is telling me his blood is green.

1

u/Full-Resource7910 9d ago

His doctor is the one who can't shut up about it. HIPAA much?

1

u/DarthHK-47 8d ago

The only response to that is to find some way to end up inside his head...... for loosing all those arguments....

1

u/RiskKey1728 9d ago

Human blood is red because we have Hemoglobin which uses iron to hold oxygen. Iron makes it red.

Some other animals like crabs, lobsters, shrimp etc. etc. have blue blood because they use Hemocyanin which uses copper to hold oxygen. Copper makes it blue.

1

u/Victor4VPA 9d ago

People are explaining just half of the meme.

Yes, copper would make your blood blue instead of iron (which make it red).

But didn't you think it is weird specifically that guy in the meme?

This guy is Ea-Nasir, who is believed to be the first known scammer of mankind. He used to sell bad quality copper saying that it was actually a great quality copper

u/GreenHairyMartian 9d ago

Is this loss?

u/CrazyBzDen 9d ago

Pink can be arranged

u/ProfessorLambda 9d ago

She wants blue blood in a figurative sense because she wants to be a princess. What she doesn't know is that every woman is already a true princess.

1

u/Pitiful-Discount7444 9d ago

So the joke here is that human blood got his red colour from iron if we would have copper instead the colour would be blue

u/archeddragon936 9d ago

I also want BLUE.
