丙酮的

Given the known reaction mechanism and general chemical considerations, we propose that nicotine, when used as the carbon source by P. putida J5, is catabolized to pyruvic acid via pyrrolidine pathway and then participates in the synthesis of vitamin pantothenate and CoA, which supply the energy for the normal functioning.
