Resources for Lipid Analysis in the 21st Century

This is a Phosphatidyl Ethanolamine (PE) molecule. This PE contains an 18:1 (oleic acid) fatty acyl chain and a 16:0 (palmitic acid) acyl chain. It is (PO)-PE. Phosphatidyl Ethanolamines form protonated molecules, [M+H]+, by electrospray ionization mass spectrometry (ESI-MS) and by atmospheric pressure chemical ionization mass spectrometry (APCI-MS). This PE also forms the diacylglycerol-like fragment ion [OP]+ and other fragments by APCI-MS and by ESI-MS/MS.

This page has been established to disseminate free copies of mass lists of PhosphatidylEthanolamines, or Phosphatidyl Ethanolamine (PE) molecular species, more formally called Glycerophosphoethanolamines (GPEtn).  They are the major components of Cephalin.

Mass lists from these pages pertain to analysis of PhosphatidylEthanolamines by atmospheric pressure chemical ionization (APCI)  and electrospray ionization (ESI) mass spectrometry (MS) techniques:

APCI-MS and ESI-MS

Data are given for Phosphatidyl Ethanolamine protonated molecules, lithium, sodium, potassium and other adducts, diacylglycerol-like fragment ions, and fatty acid-related fragments.

Mass lists are given as:

1.  Fatty Acid and Fatty Acid Methyl Ester mass list.

2.  Phosphatidyl Ethanolamine & Fragment Masses by PE name.

3.  Phosphatidyl Ethanolamine & Fragment Masses by PE mass.

4.  Masses of Adducts of PhosphatidylEthanolamines by PE name.

5.  Masses of Adducts of PhosphatidylEthanolamines by PE mass.

These tables were put together by Dr. Byrdwell in the course of more than a decade of working on lipid analysis.

These mass lists are provided here as a service to my colleagues.
