Since A4 had access to the medical database, I made the assumption that he'd have access to Sulishti anatomy and physiology and also knew the chemical structure of both their adrenaline and the toxin. So, he'd know that the poison/toxin would be chemically similar to their adrenaline. However, that may not be obvious to everyone else.
@mach--you may want to change the poison/toxin from something that's a mirror image to something that is nearly identical except maybe for a small protein molecule (or something else in the organic chem department) that is attached somewhere. The active part of the poison would be the same as adrenaline, but the extra attachment in a non-active part of the poison would prevent the enzyme that breaks down adrenaline from working on the toxin. Since the enzyme can't break down the toxin, it stays active. That way, it also wouldn't have to bounce in and out of anywhere--it would just stay in the same place and continue to cause an active response.
The reason I say this is that in most animals including humans, the mirror image of a biochem molecule is many times inactive. Think of it this way. Say you have a lock that is the same shape as your left hand. If you press your left hand on it, it will unlock and work. Your right hand is the mirror image of the left, but the right hand would not be able to fit the lock properly to unlock it. The same thing happens in the body. The left-hand version of the biochemical will work, but the right-hand version won't (or vice-versa), even though chemically they're identical. It's just how they're oriented.
@Hall-I'm very delighted to never have a chemistry test ever again.
Organic chem drove me up a wall. I could have cared less how to make a ketone out of an alcohol because I wasn't ever going to need it in Real Life. I plodded through it just to get the good grade for prof. school. Biochem at least had some relevence to what I was planning on doing so I found it far more interesting.
I've lurked a bit in the Senate Chambers. Some of the discussion there is quite interesting. If I wanted to jump into some of the arguments, though, it might take more time than I really have available for the research I'd want to do to present a decent argument. Hubby's a better debater than I am, too. I have to be mentally 'on' 100% at work (patients don't like it if you're only half way there with them
), so by the time I get home, get kids fed and homework done and then get them into bed, I'm ready for less serious thinking. Once my kids' school is out for the summer I won't have quite so many time demands so I may jump in then. The exception is the Westboro church thread, since I lived in Topeka--that'll get some comment tonight I think.
And since I've taken up enough of poor mach's thread, I should probably return it to its rightful owner and go back on topic.
