Structural identification of MGDG extracted from Synechocystis sp. PCC 6803. 1H NMR analysis of MGDG extracted from the Synechocystis sp. shows that the fraction molecule (upper panel) contains all the major structural H components δ 2.8 (diallylic methylene), δ 3.6 and 3.8 (Glycosidic H moiety), δ 4.18 (sn-1 H), δ 5.15 (sn-2 H), δ 5.25 cis ∆9 moieties present in the standard MGDG molecule (lower panel). The cyanobacterial NMR spectra are identical to the NMR spectra of the MGDG standard confirming the purity of the extracted MGDG molecule.
