Acetyl phosphate is produced during acetate fermentation. I can't find the structure for it anywhere. The precursor in this case is Acetyl-CoA, which has the the structure H3CO-S-(Coenzyme A). And of course I know the structure of a phosphate ion. So the only question really is, does that sulfur atom remain in Acetyl-Phosphate or not? A link to the structure would be most appreciated.
