Structural Characterization of Sulfoquinovosyl, Monogalactosyl and Digalactosyl Diacylglycerols by FAB-CID-MS/MS
The glycolipids such as sulfoquinovosyl diacylglycerol (SQDG), isolated from wild-type cyanobacterium Synechocystis sp. PCC 6803, and monogalactosyl diacylglycerol (MGDG) and digalactosyl diacylglycerol (DGDG), obtained from whole wheat Ñour, have been investigated by using fast atom bombardment tandem mass spectrometry (FAB-MS/MS). Collision-induced dissociation (CID) of sodium-adduct molecula...
