The molecular species of lung lecithins obtained from rabbit and rat fetuses at different days of gestation and from newborns were analysed as TMS derivatives of the corresponding diglycerides in a gas chromatograph mass spectrometer system by selected ion retrieval. In the latter part of gestation, the order of the main molecular species of lung lecithins, PC n , was PC 32 > PC 34 > PC 30 , while at an earlier stage it was PC 34 > PC 32 > PC 30 . During gestation the change of PC 32:0 , dipalmitoyllecithin, was remarkable. Ether lecithins are also discussed.
