^aThe abundance is relative to major peak in the LC/MS base peak chromatogram: + + +, base peak; ++, 50–100% of base peak; +, 10–50% of base peak. Note that the mass spectral response factors for different IPL groups can be quite different. ^bListed in order of elution: PE, phosphatidyl ethanolamine; OL, ornithine lipid; P-hex, phosphohexose.
