Reconstructed gas chromatography-mass spectrometry (GC-MS) total ion chromatogram (TIC) of the trimethylsilylated total lipid extract of (a) Kha, mummy wrappings (from base of feet) and (b) Merit, mummy wrappings (from base of feet).

Peak identities (‘n’ indicates carbon chain length; where shown, i indicates degree of unsaturation): filled triangles, C_n:i indicates fatty acids; filled squares, C_n indicates α,ω-dicarboxylic acids. C_3:0 2,3-di-OH indicates 2,3-dihydroxypropanoic acid (glyceric acid); C_4:0 3,4-di-OH indicates 3,4-dihydroxybutanoic acid (2-deoxytetronic acid); C_16:0 9,10-di-OH (t) indicates 9,10-dihydroxyhexadecanoic acid (threo isomer); C_18:1 10-oxo indicates a 10-oxo-octadecenoic acid; C_18:0 10-oxo indicates 10-oxo-octadecanoic acid; C_18:0 9,10-di-OH (t+e) indicates 9,10-dihydroxyoctadecanoic acid (threo and erythro isomers); C_18:0 11,12-di-OH indicates 11,12-dihydroxyoctadecanoic acid; C_18:2 DAGs indicate octadecadienoyl diglycerides. The letters ms represent monosaccharides and the letters ds represent disaccharides; DHA represents dehydroabietic acid.
