For Fatty Acid Abbreviations, see Fatty Acids page.

Calculated monoisotopic masses of Fatty Acids and Triacylglycerols and their adducts and fragments are based on the following atomic isotope masses:

 

1H = 1.0078250321

12C = 12.000000

14N = 14.0030740052

16O = 15.9949146221

23Na = 22.98976967

31P = 30.97376151

 

These masses are the most recent suggested isotopic masses from the National Institute of Standards and Technology (NIST) at:
