title: Phosphatidylethanolamine molecular species of fatty acid auxotroph of Escherichia coli grown with elaidate.
abstract: Monoacetyldiglycerides derived from the phosphatidylethanolamine molecular species of the fatty acid auxotroph of Escherichia coli grown with elaidate at 37 degrees C were fractionated on thin-layer plates of silica impregnated with silver nitrate and were identified by gas chromatography-mass spectrometry with an OV-17 column and gas chromatography with a Silar-10C column. Phosphatidylethanolamine was made up of the following molecular species: 1-16 : 0-2-16 : 0 (1.2%), 1-14 : 0-2-trans-16 : 1 (1%), 1-16 : 0-2 trans-16 : 1 (3.5%), 1-16 : 0-2-trans-18 : 1 (26.4%), 1-16 : 0-2-cis-16 : 1 (3.8%), 1-trans-18 : 1-2-trans-16 : 1 (13.2%), 1-trans-18 : 1-2-trans-18 : 1 (44.9%), 1-trans-18 : 1-2-cis-16 : 1 (4.5%) and trans-18 : 1-cis-18 : 1 (1.5%).
