I was just reviewing for a cell biology test and came across a figure showing the similarity of cholesterol to testosterone. Its basically the same thing except you drop a carbon side chain and a hydrogen and then move a double bond to the oxygen. This got me thinking about PP's claim that D-aspartic acid converts cholesterol to testosterone. I'm just speculating, and probably over simplifying the process here but if DAA does convert cholesterol to testosterone couldn't one make testosterone by reacting DAA with cholesterol? Maybe there is some organic chemists who could help answer this question?
