    Studying for the 3-packet cumulative exam right now and I would just like you to know how much you have done for me this year. Your videos are the sole reason I know ATP synthase in detail, voltage-gated ion channels, fatty acid degradation/synthesis and much much more. I say this on behalf of my roommate as well who is in the class with me. There were many days/nights where we would have your videos up on the plasma screen in the common room. I've been promoting your videos, I hope it is helping. Keep this up, because it is doing wonders for students like my roommate and I. Happy Holidays

      +Christopher Tavani They Christopher! Thank you for taking the time to write that! I really appreciate you promoting my videos and its great to hear that you and your room mate are benefiting from them! If you still haven't taken your finals, best of luck on them, let me know how you both do!

    Lipoamide is actually attached to the lysine residue of the E2 enzyme, not the serine. Please make this note on the video.

    • @pietroxavier2008
      @pietroxavier2008 5 месяцев назад

      true, that's why the lipoic acid becomes a lipoamide, because its carboxyl group reacts with the amine group from the side chain of the lysine. this wouldn't be possible with serine, as serine has a OH group on the side chan, which would form a ester if they were condensated.

    The lipoate is in an amide linkage with the Lysine residue of E2 actually.

  • @avtawf
    @avtawf 8 лет назад +2

    During Step 2: where did the two H+ go? You said two H+ were added on to the acetyl group to form the Hydroxyethyl-TPP complex, but when the acetyl group is removed from this complex and added onto Lipoamide, they completely disappear.

    • @simsim5265
      @simsim5265 4 года назад

    • @simsim5265
      @simsim5265 4 года назад

      I looked on Google and actually I think he made a mistake. The lone H on the carbon of the hydroxyethyl-thiamine pyrophosphate (or biphosphate) doesn't actually exist. I think it's a reduced carbon (-1).
