From the results of gas chromatography-mass spectrometric analysis methylated sugars, enzymatic hydrolysis, fast atom bombardment mass spectrometry, and proton nuclear magnetic resonance analysis, its structure was concluded to be (formula; see text) This is first report occurrence a ganglioside with 3 sialic acid residues separately linked gangliotetraosyl backbone.
