    By God, the Most High, the Great, you, professor, deserve millions of likes because of this great explanation, the idea of ​​which thousands of teachers were unable to convey.

    I was struggling horribly with this concept. Never have I felt more able to learn a concept that I have taken hours and hours looking into previously than this. Now every monosaccharide seems to be a breeze when converting to the Haworth projection! Thank you!

      ​@@wondersofchemistry Thank you. I also spent hours looking at my lecture slides only to be able to do all the examples on your video after you explained the concept before you showed the answers to the problems. You did an absolutely fantastic job explaining it, and thank you for uploading this and helping hundreds of thousands of people!

      totally I agree. and no smart talk like other videos try to make chem sounds so complex and enjoy audience suffering something only they know better or explain the unnecessary. this one just facts right to the points and critical clarification that test taker needs to know.

    i’ve been watching videos on this all afternoon long but i knew when i saw yours that this was the one haha. thank you for explaining details that are often left out, such as what atoms change their places during the switch to the cyclic form and with what motivation, why it has to be the fifth carbon atom reacting with c1 and why on earth the substitutes on the left have to go on top. will be sending this to all the chem students in my hear. thanks for making this

    This has been such an helpful video! I finally understood what substituents to look at when determining whether they are on the same side or the opposite side of the ring. One caveat I would have though, is alpha is on the SAME side, while beta sugar is on OPPOSITE side. I think the video might have reversed the two

    Brillant Video made the concept crystal clear. I was struggling with the structure of L Beta Galactopyranose as I was just remembering that if the OH is down then it is alpha. It worked until I met with L structures. Your point about the look at c6 and the anomeric carbon is Brilliant. This made it so much easier. I literally can't stress enough how mindblowing this video is Thank you man really thank you so much.

    How do you know if the #5OH group is going to be pointing up or down to form the alpha or beta anomer from the Fischer projection? I can make the Haworth, but it seems to me every fischer projection in this video has been with the #5OH pointing down, so I don't know how to make anything other than the alpha anomer.

    • @wondersofchemistry
      @wondersofchemistry  3 роки тому +2

      Hi Andrew, recall that objective of the OH functional group located on carbon number 5 of the fischer projection it to react and form an intramolecular bond with the aldehyde functional group located on carbon number 1. It is therefore non-existant after the formation of the cyclic structure and therefore has no bearing on whether the newly formed haworth structure is alpha or beta. What you should be focusing on is the relative positions of the CH2OH located on carbon 5 (cyclic structure) and newly formed OH on the anomeric carbon formed on carbon 1 (cyclic structure). If they are opposite sides of the ring (i.e., one facing up while the other is facing down) then you would be looking at the alpha anomer. On the other hand they are on the same side of the ring (both facing up or both facing down) then this would be the beta anomer. Feel free to contact me if you are still struggling with this. Regards, MG :-)

    Pneumonic to memorize placement "I'll be RIGHT down" put the function group down in Haworths projection.
    "They Left it UP to me" put the function group up :)

  • @coreyboltz4101
    @coreyboltz4101 4 роки тому

    I think there is a bit of a misleading explanation at 6:09. The H+ ion doesn't attack the O- from the former carbonyl. It has no electrons with which to perform such an attack. The electrons from the O- are what act as the base in this step, which is essentially just an intramolecular proton transfer. I know a lot of biochem/ochem professors will count off if you draw curved arrows in the wrong direction, so thought I'd mention this.
