+AvengerXP Neither is acetone if you have any idea of our metabolic cycles, nor hydrogen peroxide if you've ever taken a biology class... ever. Citric acid especially since it's the second (major) step in glycolysis (for most cells) and respiration, which high school biology should have taught you, i could go on here, but why bother lol.

@BullStengthTheories 8 лет назад

+AvengerXP And the last one especially... if you don't know the extreme importance of it, and that we need at least a couple grams of creatine from our diet daily to function properly.... i don't even know. lol.

@nyodeler6647 8 лет назад

It is kind of crazy to think about though. Having that strong of an acid running through your intestines.

@BullStengthTheories 8 лет назад

Yeah i suppose, I guess as someone with a bachelors in physiology (well and materials science) and a graduate student in biomedical engineering that learned about most of these in great detail the nuance has worn off and seem too obvious, i guess that's my bad. lol

I laughed SO HARD at the Kreb's Cycle comment. I had to study it for the millionth time in A&P a few weeks ago, now again in Biochem. I texted me friend saying, "I don't care how many times I learn the Kreb's cycle. I hate it every single time." Glad I'm not alone 😂😂😂

+Nate Conn Yes, yes it would.

@AngelValdovinos 8 лет назад

+Nate Conn sour is bitter moron

@georgelaidlaw3748 8 лет назад

***** Nope, they are distinct flavours with seperate receptors and seperate purposes. Basically bitter tastes indicate poison or at least it did hundreds of thousands of years ago. That's why things with a strong bitter taste are awful unless you are used to them and bitter foods tend to always be an acquired taste. Sourness, on the other hand, detects acidity which is useful for telling if certain foods have gone offf etc. Sourness tastes sharp, tangy and well like the flavour you get from eating the flesh of citrus fruit. Bitterness tastes earthy, burnt, unpleasant and is accompanied by an an urge to spit out whatever you have in your mouth (at least until you get used to it in a paticular food or drink). Sourness tastes sharp, tangy and can be pleasant or unpleasant depending on the strength of the flavour and what accompanies it. Often sourness is used to complement sweetness in various desserts or, of course, naturally in most fruits.

@ToxisLT 8 лет назад

+al whits there's not that much to tell about DMT, not because it's not interesting, it's uber interesting, it's because due to the &^*(*#&$(@ war on drugs, science is unable to experiment and understand these compounds. One of the very few experiments done by Rick Strassman, was written about in a book and a documentary called "DMT, the Spirit molecule". And that's about it... Thanks war on drugs, for stopping not the use of drugs, but only scientific inquiry.

But why do I have lint in my bellybutton?

@Coppertunes 8 лет назад

+Moonbeam Why is it always grey, no matter what colour of shirt you have been wearing?

@daanwilmer 8 лет назад

+Coppertunes The fibres get transported there from both your underwear and your shirt, by your belly hair. Apparently, you have grey underwear, or a colour that blends with your shirt to turn grey.

@timeparadox999 8 лет назад

+Moonbeam because you wear shirts

@Shinkajo 6 лет назад

So you can put it into your pocket with your knives. DUH!

@LuaanTi 6 лет назад

+Coppertunes Not grey in my experience, though it's certainly preferentially dark. But my guess would be that the colour is rubbed off differently (ever got blue legs from your jeans?), or is deeper in the shirt (the lint comes from fibers rubbed off the surface, dyes are deeper). It's not like the dye changes the colour of the cotton - it just coats it. What you're seeing is the colour of "clean" cotton.

@CDeruiter5963 8 лет назад

So is there any correlation between the breakdown of those metabolic processes involving formaldehyde and an increased risk of cancer?

@laffbath6740 8 лет назад

I wonder the same thing.

@Silverizael 8 лет назад

+Cooper de Ruiter No? Why would there be?

@CDeruiter5963 8 лет назад

+Silverizael In the video he mentioned that studies have shown that prolonged exposure to formaldehyde led to increased chances of getting cancer. Since he also said that small amounts are produced by the body, I was wondering if you could get the same prolonged exposure through the build up of formaldehyde in tissues. The reasoning being that cellular processes had broken down due to some unknown factor.

@Silverizael 8 лет назад

Gabriel Tzukishiro An extreme exposure to it can, but that's based on dosage. Small amounts don't cause cancer.

@todanielharrow 8 лет назад

So... If DMT is found in our body, could that possibly be responsible in part for our dreaming? And the less DMT found in us at a given time could dictate things such as the vividness of the dream, and how likely we are to actually believe that we had dreamt the previous night? Sorry if I just made people facepalm, just a curiosity.

@blunteddful 8 лет назад

I thought the same. I'm pretty sure at least one of the scientists who discovered that chemical also thought the same and... it wasn't what we thought right know... or maybe there is hope and they're trying to figure it out, who knows.

@PostSpirit 8 лет назад

I get the DMT drip in brain.

@angelpygs72 8 лет назад

+Daniel Harrow Well, that is what it actually is for. Or, at least, as far as we know. www.erowid.org/chemicals/dmt/dmt_article2.shtml So far, we have at least partially documented the release of DMT in R.E.M sleep. It releases in small amounts that give us the non addictive trip we associate with dreams. Also, as a bonus fact, apparently it releases in massive quantities when we die, causing us to go on the wildest trip a human could go on. So die happy. It's kinda important. But, although it's been proven, we can't truly know until we die. There's been some theorizing around the whole death thing, saying that when it releases when we die, that's when our soul, our consciousness, whatever, is flung out. I kind of believe this, but being a teen and all, I'm really just experimenting with beliefs. Either way, I wrote an essay on it that could totally change the way you think about this stuff because I back what I say up with facts. It's cool, and if you wanted, it's right here. docs.google.com/document/d/1RUCDoJB0-GQJjInok-XZxlSdV0sDzr46LXZulmiDn50/edit?usp=sharing

You should do an entire episode dedicated to DMT. I'm very curious why this powerful psychedelic is made by our body since there isn't a clear answer to it. Also want to know if it's harmful since it's an extremely illegal substance

@clintbandura9018 8 лет назад

it's only illegal because it wakes you up to the injustices in every aspect of your everyday life

@butternutsquashpie 8 лет назад

+Pierce Connors DMT is a simple molecule very closely related to tryptamine and therefore tryptophan (one of the twenty-two key amino acids needed for your body to function in general). Tryptamine exists and is also mildly "psychoactive" and the dimethylated analogue would logically exist due to the methylating enzymes that your body produces to methylate specific compounds. Occasionally, stuff goes past it like DMT. It is illegalised by the US government when they blanketed all psychedelic compounds as it was closely related to insurrection and protests (and hippies) back in the 70s... what with the Vietnam war.

@SoulDelSol 7 лет назад

Pierce Connors it's similar in structure to serotonin and melatonin. but legal status =/= safety. you'd have to look more into history of drugs in America to understand war on drugs

@udtheaesir 6 лет назад

It's not harmful in the least. Blame the DARE program and the war on drugs for that bad rep to psychedelics in general.

Acetone does get used in the body, through detoxification in the liver it can be converted to precursors that can be pushed through gluconeogenesis... however this is slow so a lot of it is exhaled or peed out due to it being very volatile are easy to escape the body.

@Edgewalker001 8 лет назад

+Seth Winfrey The reason people get the munchies is basically this. What most people don't know is that THC, the active ingredient the smokers are looking for, breaks down into a god awful mess of different compounds with different effects and different half lives when it actually gets to your liver (If you thought the Krebs cycle was bad, you don't want to memorize those, believe me...). And some of those act as appetite enhancers.

@ASTCify 8 лет назад

There're a lot of cuts and edits. Each cut comprises of about 1-3 sentences. So even if they don't use a teleprompter, they'd only need to memorize a few sentences per cut. Lots of youtubers do that. It's people who can go on for 15-60 unedited minutes, for example TED-talk presenters, that are script-memorizing beasts.

+Gamerguy8585 This may sound like a weird answer but exercise and a healthy diet.

@Camboo10 8 лет назад

+Gamerguy8585 Not a weird question at all people ask it all the time. SciShow made a video on it before but I also recommend looking at Healthcare Triage's episodes on the subject.

Fat is an energy store. You get rid of one type of energy by converting it into a different type. A common choice from the resulting energy is kinetic energy.

if stomach juice is acidic then why is it when we vomit it never burns a hole in the floor

@howardnickerson2853 8 лет назад

Stomach acid is strong just not that strong.

@Silverizael 8 лет назад

+Alama Joradon The amount of acidity required to do that would burn through your stomach as well. Stomach acid is not anywhere close to that.

@WorldsMostWated 8 лет назад

+Alama Joradon You're... you're not being serious are you?

@bbruinenberg 8 лет назад

+Alama Joradon My guess is because it's mostly diluted at that point. The food and saliva dilute it enough to prevent it from doing any damage outside your body. That is not to say that it lost it's acidity though. If you ever had a painful burning feeling in your stomach, you know how dangerous it is when stomach acid leaved your stomach. It is not a nice feeling and the acidity is definitely noticeable.

@feynstein1004 8 лет назад

+Alama Joradon Because it's too dilute. Did you even watch the video? He said that the pH of stomach acid is the same as battery acid and you don't see battery acid burning holes through everything.

Some Emergency Medical Technician second gueesed my knowlegde of Acetone in our breath causeing it to be fruity. Thank you SciShow for affirming this knowledge. Your the best. Make more videos on Cannbis world. Awesome research on the Endocannabinoids.!!!!!!!!! I will remeber this forever!!!!!! Best,

Formaldehyde? No duh. Taking O-chem right now, it's actually a really common organic product or byproduct. O-chem... oh dear God, my O-chem final is wednesday morning isn't it?! And heck yeah Acetone is in my blood; that stuff smells amazing! I tried to avoid it in lab, but I don't exactly ensure I won't get a tiny whiff or two... ;) The only thing even better is hexanes, like for TLC development. *FUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu...*

@micahphilson 8 лет назад

Wild4lon In all honesty, that'll probably be the only reason I'll be able to pass this final. Gonna need my brain to self-produce the hard stuff...

@OfNaught 8 лет назад

+Micah Philson Ah, I finished my final Ochem course last quarter. Those were good times... maybe, haha. I'm glad now though, since I now actually more or less understand what all this stuff is. Good luck on your final. O7

@micahphilson 8 лет назад

OfNaught I really like O-chem, it's just really difficult. It would take me a few years of classes just to actually understand the notes from this year alone. I hate the college system. I'm only now understanding concepts in gen-chem I had over a year ago. They don't actually teach you things very well at all. Well, that and I'm taking 14 credit hours this semester, but with labs, reci's, etc, I'm actually taking 24 hours in classes. Lab took more time outside of class than any lecture!

Yannik Mroos All my uncles are over 6' and went bald. All but my father who is 5'10 and full head of hair. I'm the tallest male in my family at 6'5'', and my hair is thinning already, and has been for few years. For some reason being tall and bald skipped my dad. Although, his father died in his 60s or 70s with a head full of hair still too, so.

@FlameXRLD 4 года назад

I heard somewhere that the dmt your body makes is for times where important things happen suck as birth or death or near death experiences as you go through this odd state where everything seems weird which seems to be facilitated by dmt being released into the bloodstream but I’m not sure, does anyone else have any thoughts?

The thing is that, considering the amount of water in my body and the Ka of HCl, there realistically isn't any significant amount of HCl in my body -- there may be hydronium ions and chloride ions, but the hydronium could as easily be associated with another anion as with chloride.

I used to take night classes and had to drive home late at night. On more occasions than I'd care to admit I would make the 25 minute drive and wake up in my driveway at home and barely remember how I got there. Irresponsible and scary... Yes. But also amazing. Is there any science behind how we can do that and what is happening in our brains during human autopilot?

@ErzengelDesLichtes 8 лет назад

#4, Hypochlorous Acid is used as a household cleaner and by our white blood cells? So, when we talk about bacteria becoming hardier to household cleaners because we use them so much (only those that are hardy survive to reproduce), does that mean we're also evolving bacteria that's hardier to our immune system?

Does the body start producing more Creatine if your an active individual? when i was a new lifter i responded really well to supplementing now that i have a decent level of strength i get nothing out of it.

@ArtFreak17 8 лет назад

I was kind of hoping runner's high would get mentioned with number 9. Since a really fun endogenous cocktail of psychoactives is involved in the phenomena; there's opiod (those endorphins you hear a lot about), stimulant, and cannabanoid action going on to get one in a pretty awesome state of bliss. ... I bring this up, mostly since I've come to appreciate the experience a lot since I started exercising in September last year. It's a nice treat, in addition to the dopamine involvement, and making HPA axis function more healthily (the system of hormone production involved in stress- one reason why exercise can help take the edge off anxiety). (Also have some idealogical/personal reasons not to take exogenous psychoactives in a recreational context... sans caffeine. So that's another win for me going for this sort of experience.)

Michael, I rember hearing long time ago, thet a small amount of ethyl alcohol is produced in the body as a byproduct of metabolism, maybe an ounce per day, and this is why the liver can break it down atall, true or no?

@smoko1994 8 лет назад

Maybe DMT is produced while we sleep as a byproduct of our brain (and the rest of nervous system) "cleaning" itself, removing the waste, hence found in cerebrospinal fluid. But since it's a powerful psychodelic, it stimulates some sense input processing centers in the brain, therefore dreams occur. Basically like naturally dropping acid while sleeping.

@NextGenAge 8 лет назад

It is said that DMT is responsable for dreaming because we used as a drug it can create profound psychedelic experiences and create new connections in the brain. Resting and dreaming, with small natural amounts will help to place memories and reflect on them in different ways

The Kreb's Cycle only got interesting for me when I realized that it's the exact opposite of photosynthesis. Instead of getting energy out at any given step, plants add energy from sunlight to store it going the other way.
