Electrospray ionization-quadrupole ion trap mass spectrometry (ESI-QITMS), either in positive- or in negative-ion mode, has been used to establish the chemical structures (chain length, degree of unsaturation, positional distribution) of the fatty acids attached to the primary (sn-1) and secondary (sn-2) hydroxyl groups of the glycerol moiety of natural monogalactosyl- (MGDG) and digalactosyldiacylglycerols (DGDG), isolated from the freshwater dinoflagellate Glenodinium sanguineum and from a… Expand

Mono- and digalactosyldiacylglycerol composition of dinoflagellates. IV. Temperature-induced modulation of fatty acid regiochemistry as observed by electrospray ionization/mass spectrometry
TLDR
DGDG is modified preferentially over MGDG and TGDG in response to growth temperature by modulating the sn-2 fatty acid of DGDG between the 18:5(n–3) and 18:4(n-3) forms, while theSn-1 fatty acid, 20:5 (n– 3), remained constant. Expand
