a
MHDAG, DHDAG, TriHDAG and TetraHDAG are mono-, di-, tri-, and tetra-hexosyldiacylglycerol, respectively.
b
These m/z values are for strain FRIFI. The values for other species may vary slightly.
c
Although these lipids have been detected in R. lituseburensis and R. ilealis, nomass spectral data are available.
