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.

Adducts of PhosphatidylInositols in COLOR are not usually observed to an appreciable extent.

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:
