Mass spectrometry identification of PtdOH and CDP-DAG accumulation following the removal of the glycerol supplement. The identity of the two new polar phospholipid species that appeared in glycerol–starved cells was confirmed by mass spectrometry of the phospholipid fraction in the presence (A) or absence (B) of the glycerol supplement. Samples were prepared and analyzed by mass spectrometry as described in Methods.
