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:
