neopinone, which is formed most likely by demethylation of the vinylether of thebaine exists in the plant cell in a thermodynamic equilibrium with codeinone. The presence of the codeinone reductase/NADPH system shifts this equilibrium quantitatively in the direction of codeine, which either accumulates in the latex of the poppy plant or is further demethylated at the 3-OCH3 group yielding morphine
