Chemical ionization mass spectrometry with nitric oxide as the reactant gas has proved to be an efficient tool for locating the double bond in monoalkenylglycerols of type HO‐CH 2 ‐CHOH‐CH 2 ‐O‐(CH 2 ) n‐1 ‐CH=CH‐(CH 2 ) n‐2 ‐CH 3 . These monoalkenylglycerols were extracted from the liver oil of the shark Centrophorus squamosus , which lives at depths ranging from 1000 m and deeper. The presence of characteristic acylium ions R 1 CO + and/or R 2 CO + allowed location of the double‐bond position.
