Location of deep‐sea shark (Centrophorus squamosus) glycerol ether lipid double bonds by nitric oxide chemical ionization mass spectrometry

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‐CH2‐CHOH‐CH2‐O‐(CH2)n‐1‐CH=CH‐(CH2)n‐2‐CH3. These monoalkenylglycerols were extracted from the liver oil of the shark Centrop...

Zusammenfassung:	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‐CH2‐CHOH‐CH2‐O‐(CH2)n‐1‐CH=CH‐(CH2)n‐2‐CH3. 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 R1CO+ and/or R2CO+ allowed location of the double‐bond position.
