Random interesting thing:

Birds also need sunlight to synthesize vitamin D, but their skin is blocked by their feathers. So the chemical precursors to vitamin D are in their "preening oil", a substance they secrete from a gland and rub on their feathers with their beak, an activity called preening. The sunlight hits it and forms the vitamin D, and they end up swallowing enough of it the next time they preen. The preening oil also contributes to the feather's waterproofing and keeps them flexible.

That's pretty cool. Random interesting facts are the best.

Bananas come from the sun, it's simple.

[–] [email protected] 56 points 3 days ago (7 children)

Is light just really small bananas bouncing off of everything?

[–] [email protected] 8 points 3 days ago (2 children)

And if you shine a beam of light through some slits, the banans split.

[–] passiveaggressivesonar 1 points 1 day ago (1 children)

Only if I take your word for it though right? If I check myself...

[–] [email protected] 1 points 1 day ago

Caught me slipping!

[–] [email protected] 1 points 3 days ago

It's also a smoothie.

[–] seven_phone 11 points 3 days ago (1 children)

Well that is a very simplified view of nature, in reality they do not always bounce and banana is just a catch all term for any elongated fruit.

[–] ivanafterall 5 points 3 days ago (1 children)

TIL a cucumber is a banana.

[–] [email protected] 2 points 3 days ago

SCIENCE!

[–] [email protected] 6 points 3 days ago

sounds right

[–] [email protected] 2 points 3 days ago

Yes, that is why the banana phone was such a revolutionary invention.

[–] Iheartcheese 3 points 3 days ago (1 children)

Why do you think we measure things by light years?

[–] ewigkaiwelo 5 points 3 days ago (1 children)

Only distance, we measure things in bananas

[–] Klear 5 points 3 days ago (1 children)

A banana is about 0.6 light-nanoseconds long.

[–] ewigkaiwelo 5 points 3 days ago* (last edited 3 days ago)

It takes light approximately 8,404494e11 bananas to travel from the surface of the sun to the earth (that's like 840449400000 = eight hundred forty billion four hundred forty nine million four hundred thousand bananas (English is not my first language, not sure if the numerals are supposed to be plural))

[–] [email protected] 1 points 3 days ago

Only if it's yellow light.

[–] [email protected] 1 points 3 days ago

i mean photons don't really have a shape so... it can be if you want it to be

[–] [email protected] 7 points 3 days ago

That's why they're yellow.

They are constructed by the sun and made up of it's dead breathren

A vitamin is any essential dietary component, which is organic (otherwise it would be a mineral nutrient), and is not a fat, protein/amino acid, or carbohydrate (although carbohydrates are considered non-essential).

Vitamin D is conditionally essential. If you have enough sunlight, your body can synthesize it.

[–] [email protected] 31 points 3 days ago (2 children)

How does the body absorb the sun's bananas though? Let's see you weasel your way out of that, science nerd!

[–] saltesc 40 points 3 days ago (1 children)

You apply this

[–] [email protected] 9 points 3 days ago (1 children)

... oh damn.

[–] [email protected] 2 points 3 days ago

You'll love this

[–] seven_phone 13 points 3 days ago (1 children)

I actually can raise my hand for this one, the impact with the skin surface emulsifies the outer banana layer which is then readily absorbed by the pore system. Bananasplitsynthesis is a very well understood process.

[–] [email protected] 4 points 3 days ago

That's good stuff. Bravo

[–] ewigkaiwelo 4 points 3 days ago (1 children)

I've heard somewhere that maybe initially vitamin the word comes from "vital amino acids" => vita(l)min(o).. and any substance from a living creature would include amino acids anyway because they have DNA RNA and such

[–] Jesus_666 13 points 3 days ago* (last edited 3 days ago)

Vita + amine, actually. Amines are compounds with an NH₂ group; amino acids are a subset of that.

The person who coined the term thought he had isolated an amine that was effective against a certain disease. What he had actually isolated was neither an amine nor effective against that disease but was actually a different essential compound. (He was looking for what we now know as thiamine but had actually discovered niacin.)

The name "vitamin" stuck around despite the fact that most vitamins aren't amines.

[–] MissJinx 3 points 3 days ago (3 children)

Didn't explain it. Jus said "it's something your body needs"

[–] [email protected] 9 points 3 days ago

There was actually just a very detailed gastropod episode on this, but the tl;dl version is that a vitamin isn't a specific thing the way a protein or a carbohydrate is. It's anything that the body needs in small amounts that isn't something else

[–] [email protected] 1 points 3 days ago

Because that’s the definition: an essential organic compound that is not a mineral, fatty acid, or amino acid. It’s the “everything else” category for essential nutrients.

[–] [email protected] 1 points 3 days ago

Brawndo, got it

[–] RememberTheApollo_ 15 points 3 days ago (1 children)

Same person: “I never eat vegetables.”

[–] affiliate 2 points 3 days ago (1 children)

i don’t need to know what a vitamin is in order to eat things that have vitamins. to be honest i don’t even really know what calories or protein are, but i probably still eat things that have them. and vegetables too.

[–] DreamlandLividity 10 points 3 days ago* (last edited 3 days ago) (2 children)

I have to tell you what calories are, because it sounds so incredibly unhinged.

Calorie is a physical unit of energy. For food, calories are measured by removing all water from the food, turning it into powder, enclosing it in a metal container, submerging said container in water, measuring the temperature of the water, then setting the food on fire, which causes it to explode, and measuring the temperature of the water again.

The explosion warms up the water a bit. By measuring how much it warmed up, you can calculate how much energy the food released when it exploded and that is the foods calories.

So calories basically tell you how explosive a food is.

What does that have to do with anything? Who knows.

[–] affiliate 5 points 3 days ago

that’s pretty sick. i should start blowing up my food too

[–] [email protected] 1 points 3 days ago

One mcdonalds meal has enough calories to level a city block.
