This is a Phosphatidyl Serine (PS) molecule. This PS contains an 18:1 (oleic acid) fatty acyl chain and an 18:0 (stearic acid) acyl chain. It is (SO)-PS. Phosphatidyl Serines form protonated molecules, [M+H]+, by electrospray ionization mass spectrometry (ESI-MS) and by atmospheric pressure chemical ionization mass spectrometry (APCI-MS). This PS also forms the diacylglycerol-like fragment ion [SO]+ and other fragments by APCI-MS or by ESI-MS/MS. |

This page has been established to disseminate free copies of mass lists of PhosphatidylSerines, or Phosphatidyl Serine (PS) molecular species, also called Glycerophosphoserines (GPSer) . Mass lists from these pages pertain to analysis of PhosphatidylSerines by atmospheric pressure chemical ionization (APCI) and electrospray ionization (ESI) mass spectrometry (MS) techniques: APCI-MS and ESI-MS Data are given for Phosphatidyl Serine protonated molecules, lithium, sodium and potassium 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 Serine & Fragment Masses by PS name. 3. Phosphatidyl Serine & Fragment Masses by PS mass. 4. Masses of Adducts of PhosphatidylSerines by PS name. 5. Masses of Adducts of PhosphatidylSerines by PS 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.

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. |
