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.

Calculated monoisotopic masses of Phosphatidyl– Inositols 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:
