And as yesterday's faces when I suggested this would indicate, a beef tongue, zuchini, and anchovie pizza would have few takers in civilized gaming.
ATP vs DNA is very chicken-and-egg in current evolutionary theory. In ATP there's a ribose sugar attached to the ATP at a convenient aromatic N and three phosphates in a line attached to the ribose. And in DNA there's an adenosine with a ribose sugar attached at a convenient aromatic N and a phosphate attached to the ribose. The difference between ATPness and DNAness is more phosphates attached to the ribose to form a chain of phosphates and riboses with nucleotides hanging off like loogies.
The way to get the adenosine and the caffiene is the same. Take a purine double-ring and stick stuff on it. And the body just does that in protien metabolism. It just... doesn't make caffiene for some unknown reason. Not because it's hard, it's really not. But because early life favored adenosine over caffiene.
Though I really bet in a liquid ethane environment like Titan (and I so firmly believe there's life on Titan it's not even funny) caffiene would be the dominant of the two because it's less polar.
Hydrogen bonding confuses people because it's not really an exact bond. It's not a covalent bond, it's not an ionic bond. It's more like the sharing of a skank. Proton (the skank) accepts charge (expensive favors) from two different molecules (the suitors) at the same time. Then when the molecules unbond the skank goes with one suitor and hands the loser back his favors.
What are your thoughts on peroxide-based life? Peroxide as opposed to water, I mean.
