Quote:[Patrick; Any biochemistry text will draw chemical reactions with circular arrows for each reactant. Things keep cycling each other. With an ET developer, it can either recycle both ingredients or have one 'pump' the other in activity.]

I have known since high school that if it is possible for the ingredients of a solution to form more than one set of compounds, they will be formed given the right conditions. Of course, if you want a particular set of compounds to be formed you have to know the conditions. I make prety good coffee because I know the right conditions to avoid the "fusel oils". Whether or not that is what they really are, I don't know
