Acetylcholine (ACh) biosynthesis pathways are still unclear. In Torpedo electric organ the best precursor of acetyl moiety of ACh is acetate (2) as in the neuromuscular junction of the rat (1). Morot and Diebler (4) found an acetylCoA synthetase activity in the cytoplasm of the electric organ cells, but they could not separate any labelled acetylCoA from labelled acetate.
