The structural elucidation of the two positional isomers of a mono-glucopyranosyl mono-acyl glycerol derivative from Cystobacter fuscus (Myxobacterales).
The structures of two glycolipids produced by Cystobacter fuscus Cb 685 have been determined by 1H-NMR spectroscopy including 2D-techniques, as the positional isomers 1- and 2-isopentadecanoyl-3-beta-D-glucopyranosyl-X-glycerol. The chain length of the fatty acid residue determined by 13C-NMR spectroscopy has been confirmed by negative ion FAB-mass spectrometry.
