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:
