Fig. 1. Negative ion ESI/MS spectra of GlcNAcDRG and EtnP-GlcNAcDRG species from C. sporogenes strain ATCC 3584.
Pla, plasmalogen species. The structure of the plasmalogen form of EtnP-GlcNAcDAG (30 : 1) is shown. The number before thecolon is the sum of the chain lengths and the number after the colon is the number of double bonds.
