    Sir, you have no idea how remarkable your explanation was. I wandered across the length and breadth of TH-cam trying to understand this "Fischer to Haworth" conversion thing before I stumbled upon your video. God bless you!

    THANK YOU SO MUCH! I just had a food Chem exam and did very poorly and was feeling so dumb. Thank you for explaining it so clearly. I feel like now I can do better on the next exam!

    I am a medico(mbbs Student) learning biochemistry .
    I didn't get clear idea of cycling structure till now.
    But now it's clear for me.
    Thanks

  • @renoleevans
    @renoleevans 2 ปีที่แล้ว +4

    So if on the fisher projection, you stated at carbon 5, the hydrogen (on the left) is pointing down. Shouldn't it be facing up if it has been rotated 90 degrees? OH down, H up? Or because of the OH pyranose attack on the carbonyl carbon, it was rotated?

    Nice up until the part where CH2OH moved from position 6 to position 5. How exactly did that happen. And how did you say that CH2OH is pointing upwards? I need a more elaborate explanation of what happened at C5 and C6. Thanks.

      I was just about to say that the sugar hydrogenated itself. Hydrogenation means to stick a hydrogen in place of a double bond, which is what just happened.

  • @jennarae1362

    this is was okay, it would be nice if you followed the convention of arrows starting with electrons and pointing to the electron receiver. but i suppose that's just how it makes sense in my head. otherwise this was helpful!
