Taking Lipid Analysis into the 21st Century |
|
This is a triacylglycerol (TAG) molecule. This TAG contains two 18:1 (oleic acid) fatty acyl chains and an 18:2 (linoleic acid) acyl chain. It is OLO. Triacylglycerols form protonated molecules, [M+H]+, by atmospheric pressure chemical ionization mass spectrometry (APCI-MS). This TAG also forms the diacylglycerol-like fragment ions [OO]+ and [OL]+. |

This page has been established to disseminate free copies of mass lists of Triacylglycerols, also called Triglycerides. Mass lists from these pages pertain to analysis of triacylglycerols by atmospheric pressure chemical ionization (APCI) and electrospray ionization (ESI) mass spectrometry (MS) techniques: APCI-MS and ESI-MS Data are given for protonated molecules and ammonium adducts of triacylglycerols, and diacylglycerol-like fragment ions formed by triacylglycerols. Mass lists for triacylglycerols are given as: 1. Fatty Acid and Fatty Acid Methyl Ester mass list. 2. Masses of Triacylglycerols arranged by TAG name. 3. Masses of Triacylglycerols arranged by TAG 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.

Update!! The Fatty Acid and Triacylglycerol pages have been updated to include very long chain fatty acids (>20 carbons), plus ammonium adducts, [M+NH4]+, lithium adducts, [M+Li]+, and sodium adducts, [M+Na]+, of Triacylglycerols in electrospray ionization mode. See AAA, AAB, and ABC pages for updated mass lists. |
