    besides being less expensive, another advantage of saturated fatty acid is that their single bonds are much more resistant to oxidation than double bonds, so they don't go rancid as fast as unsaturated fats.

  • @zoeydeu2261
    @zoeydeu2261 2 роки тому +2

    The food industry also bleaches the hydrogenated fat afterwards to give it a nicer appearance (as good as filtering may be, it doesn't completely render the transfat white). For margarines they use to add yellow coloring to mimick the look of butter

      @@unperrier5998 - *Here, the best answer in the world and EASY too... Temperature = Radiation. The higher the radiation, the higher the heat which turns into what is known as 'Electron(s)'. Through "Electrons", then come what is known as Ionic Bond. Then too many electrons, IT separates the bonds and that is how IT becomes "Liquid". Basically, "Elections" wiggles the molecules apart.

    Hi Ben: Great demonstration and explanation. I liked your low pressure compensator/monitor glove setup; that's a great way to be able to maintain and monitor a slight positive pressure on an experiment and not to pop stoppers, tubing, etc. off your line. For a setup requiring a bit more purity you could exchange the glove for a thin viton diaphragm or better a small stainless steel bellows. In addition to our evolutionary preference for saturation it also gives produces, as you said a spreadable, consistency and the best example I can think of is peanut butter where hydrogenated fats are added to make it spreadable and so the oil won't separate opposed to the "natural" peanut butter that's a bit "loose." Cheers, Mark

    Quick note: at 5:40 you drop a stir-bar into the flask, directly on the magnetic stirrer. This should be avoided, since it can shatter the glass (even relatively thick borosilicate glass...). What we used to do in my O-Chem laboratories back in undergrad was to slide the bar in while the flask is in an angle, and never above a magnetic stirrer.
    Aside from that, though - neat video!

    Food scientist Alton Brown talked about types of fats in an episode of "Good Eats", and he used balloons to illustrate saturation. It was a mind-expanding experience for me, because I finally saw the relationship between electricity and chemistry. The big hydrogen balloons repelled each other. Well really, they had a radius, and since two balloons can't overlap in three-dimensional space, their latex borders push against one another. But this is analogous to hydrogen ions repelling one another, which is just a phenomenon of electric fields and like-charged particles. The even distribution of hydrogen ions along a saturated fatty acid results in an overall straight line. (A zig-zag, but when you zoom out, it has a definite origin and destination trajectory that are 180 degrees apart.) But when he popped a balloon, it showed there was an opportunity, or rather electrical incentive, for the whole thing to bend. The side with more hydrogen ions took the "outside" of this bend as they repelled each other. Or perhaps more accurately, the side with the missing hydrogen ion became shorter because there was less repulsion. This makes it a little more complicated for the triglycerides to get into inter-molecular formation, and with the kinetic distraction of heat, it's even more difficult. Meaning the threshold for the temperature at which the molecules can line up, its "solid temperature tolerance" if you will, goes down. I know this is very basic stuff, but I didn't really get it until I saw that visualization.
    It's like that game "Perfection", where there's a timer and you have to put all the shapes into their respective slots. When the timer goes off, the whole apparatus pops up and makes the pieces go everywhere. So to win, you have to put the pieces where they go before that happens. Saturation of fats is like reducing the variety of pieces, making it easier to put them where they go, while increasing the temperature is like speeding up the timer, making it harder to do that. And of course "winning" is analogous to making a solid. And unlike human players who can get better with time, molecules are indelibly subject to their circumstances and do not benefit whatsoever from experience.
    Also, that apparatus with the knobs to switch between evacuation and hydrogen infusion.... did you make that yourself? After seeing so many of your videos, it seems like the kind of thing you could and would make yourself.

    @unperrier5998 3 роки тому +1

    Thanks for the video, blue thumb is in order :)
    That said, it's better you focus on physics and leave medecine to MD :)
    For a start, unlike what he said in the video, saturated and unsaturated fat don't end up in arteries. They're processed in our GI tract and eventually metabolized in the liver. At the end of the day triglycerides and cholesterol carried by lipoproteins (like chylomicron which turn into HDL and then become IDL and finally LDL) are the only two fats carried by the blood. Triglycerides are small and float easily. Imagine if any fat we ingest ended-up in the blood, remember the blood is an aqueous medium/environment... you'd end-up with phases like in a vinaigrette!
    Actually unsaturated fats (oils, even olive oil!) are worse for health than saturated fats because of that double bond (polyunsaturated oils even have several of them!) which is prone to attract oxygen molecules which renders the fat "rancid" (oxygenated) and which now acts as a free radical that will cause all sorts of troubles, thin particular it causes inflammation in organs like the liver.
    This oxygenation occurs within hours. How long do you usually keep your oil in the cupboard? ;)
    That said any type of fat is bad when consumed with glucose because of glycation: that's the only case when naturally occuring saturated fat (not hydrogenated) is bad, unfortunately every study assumes the American Diet which is high in carbs.... hence they conclude that saturated fat is bad, instead of the more logical conclusion that carbs are bad. He mentionned cavemen and our propension towards saturated fats: well, cavemen didn't have a lot of sugar and processed food laying around like we do since the 1950s. Instead they had meat and fats and a few vegetables and not a lot of carbs (fructose is directly sent to the liver to be metabolized and stored as fat), that's why saturated naturally fats occuring with meat were not harmful to them and they develop a keen sense for saturated fats that we inherited from them.
    (disclaimer: I'm not an MD but I like the topic)

    If I remember right, you can use a glass syringe with glass wool packed in it followed by celite to better filter out the catalyst. Essentially just pressure filtration through a thicker and finer filter.you can have it before or after the injection port on the syringe. A heated centrifuge would probably work better for recovery though.

    In high school I was talking with my chem teacher about a similar process on oil spills. My idea was to use hydrolysis of salt water to change the structure of the crude oil to make it easier to clean. I've always lacked the means due to cost,time, and lack of equipment to test my theory. If you could i'd be highly interested if you could test the same process but with used motor oil rather then olive oil and using salt water as your solvent.

    • @SG-ds8pr

      Electrolysis wouldn't change much of crude oil if any at all. It's mostly comprised of cyclic alkanes, aromatics and C1-C60 straight chain alkanes. The best thing to use would be a hydrophobic nonpolar absorbing agent.

    2- I fully understand that it isn't healthy, but if you completely remove your catalyst, would your end product be edible?

    In your opinion, what's the ratio V2/V1? It's fair to assume it gets dense, but how dense.. And can this serve for transportation purposes (and waste management, easier to deal with solids than liquids) ? (reduce volume ==> more can be transported each trip).
