  • there a walking chemist of toxins

  • @820423 It isn't because they are closely related. The key as to why those two molecules are similar, is probably because they mimic a molecule released by the synapse which fits in a receptor in the receiving neuron. The N and O structure probably fits this receptor perfectly, in a way that blocks the transmitter molecules from entering, and thus changing the neuron's action potential. This would essentially block the firing neuron. Just guessing though - it is a fascinating question-

  • Holy crap, drawing intricate structures on the vial? I synthesized a simple biaryl and couldn't be arsed to draw it.

    I feel severely outclassed; well played good sir.

  • If anyone knows, or feel secure in offering a sound speculation, please, do not hesitate. Mental question-bombs are dangerous afflictions. If left untreated, they can cause nausea, skin-rash and pseudo-science.

  • Always the one nitrogen atom, the oxygen atom and the exact spacing between.

    Just like anatoxin-A. Why is that? Why this concept over and over again? One is from a frog, the other from algae. Both kills by paralyzing muscle control. It seems like the achilles heel , for land-living animals.

    Does these frogs and the blue green algae share any obvious evolutionary relations? What other organisms use this concept in their poison?

    Oh, it feels like I just had a question-bomb go off in my head!

  • Is Dr. Stockman a biochemist?

  • we are breeding them at our school

  • @imover18gotityube its stereo... both speakers

  • @Skindoggiedog You don't stick it through the frog. You just need to rub it on the frog.
