This is a Glycerophosphoethanolamine (GPEtn) molecule. This GPEtn contains an 18:1 (oleic acid) fatty acyl chain and a 16:0 (palmitic acid) acyl chain. It is (PO)-GPEtn. Glycerophosphoethanolamines form protonated molecules, [M+H]+, by electrospray ionization mass spectrometry (ESI-MS) and by atmospheric pressure chemical ionization mass spectrometry (APCI-MS). This GPEtn 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 Glycerophosphoethanolamine (GPEtn) molecular species. Glycerophosphoethanolamine is not a single molecule, but is a class of molecules, which are informally called PhosphatidylEthanolamines, or Phosphatidyl Ethanolamine (PE) molecular species. They are the major components of Cephalin. Mass lists from these pages pertain to analysis of Glycerophosphoethanolamine by atmospheric pressure chemical ionization (APCI) and electrospray ionization (ESI) mass spectrometry (MS) techniques: APCI-MS and ESI-MS Data are given for Glycerophosphoethanolamine 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. Glycerophosphoethanolamine & Fragment Masses by GPEtn name. 3. Glycerophosphoethanolamine & Fragment Masses by GPEtn mass. 4. Masses of Adducts of Glycerophosphoethanolamine by GPEtn name. 5. Masses of Adducts of Glycerophosphoethanolamine by GPEtn mass. These tables were put together by Dr. Byrdwell over the course of several years of working for the Agricultural Research Service. These mass lists are provided here as a service to my colleagues.

Disclaimer: Not all fragments or adducts listed here are observed from every class of phospholipid. Every possible adduct and most fragments have been listed here for the sake of thoroughness, whether they are actually observed or not. The page for each phospholipid class will be tailored as time permits. |
