    First comment I ever left on a youtube video, just wanna let you know that your lectures are really helping me a lot with biochemisty since they are well structured and easy to follow through. Plus your drawings are perfectly visible, which is definitly not the case for every ''youtube lecture''. Thanks a lot and keep up that good work!

    Your lectures are literally my go to. You do the connections, you give the overview, there's no searching no pounding for answers.
    Thanks for your fantastic channel.

    Hi There! Question: Why is it called the Galactose-Fructose Pathway? It doesn't seem like fructose in involved. More seems like a Galactose-to-Glucose Pathway?

    • @abdibrainsteaser6702
      @abdibrainsteaser6702 4 роки тому +2

      It is because the glucose formed is also converted to fructose to continue with glycolysis

    • @whatsnew14
      @whatsnew14 2 роки тому

      Might be glucose one phosphate will convert into fructose one phosphate and will follow the same pathway with he discuss earlier.

    Great lecture! for funsies/clinical tie in: the differences between nonclassical v. classical galactosemia. Since you also talked about fructose: essential fructosuria and hereditary fructose intolerance. (Not sure if you have a time limit on your lectures? Clinical ties in helps me remember the pathways better.)

    Just one question: At 13:32 the substrate of Phosphoglucomutase is presented as G-1-P. But didn't the previous reaction yield UDP glucose?

    • @whirlproof
      @whirlproof Рік тому

      from what i understood, it just regenerated it (kinda in the way enzymes work, they aren’t used up in the yield reaction)
      so udp glucose just goes to exist in the cell, while phosphoglucomutase acts on the product of the second reaction - glucose 1-phosphate

    Good afternoon,
    I'd very much like to understand where on the fructose metabolism is the flaw that leads to fructose malabsorption... I have fructose malabsorption, as well as lactose malabsorption, and i'm trying to learn what's happening to my body. I'd be very greatfull if you'd be kind enough to give me some instructions on the matter, for I'm having a hard time finding good material online, such as yours is.

    Where does the first UDP glucose come from before any of the “UDP galactose converting into UDP glucose” reactions?

    • @peybak
      @peybak 10 місяців тому +1

      A year late but Galactose1p is converted to UDP Galactose via a UDP transferase. Then UDP galactose is epimerised to UDP glucose via epimerase. UDP glucose then dumps its UDP to another galactose and itself becomes G1P which then is converted to G6P by a mutase. So overall it's a cycle.
