* To whom correspondence should be addressed. Verots S3 cells derived from the African green monkey kidney were revealed to contain nine types of sulfoglycolipidsby incorporati ng [35S]sulfate. These sulfated glycolipids were separated by DEAE-Sephadex column chromatography and preparative thin-layer chromatography. The major sulfoglycolipids were characterized by using thin-layer chromatography, gas-liquid chromatography, mass spectrometry, solvolysis, thin-layer chromatography immunostaining, and nuclear magnetic resonance spectra as follows:V1 , SM4s (GalCer I3-sulfate);V2 ,SM3 (LacCer II3-sulfate);V3 ,SM2a (Gg3Cer II3-sulfate); V4, globopentaosyl ceramide sulfate (Gb5Cer V3-sulfate); V5, (Gg4Cer II3-sulfate, IV3-NeuAc); V6, SB1a (Gg4Cer II3, IV3-bis-sulfate); and V8, (Gg4Cer II3-NeuAc, IV3-sulfate). Both V5 and V8 were sulfated gangliosides comprising both N-acetyl neuraminic acid and sulfate, and this was the first report on V8. A minor component V7 was identified as SM1a (Gg4Cer II3-sulfate) based on its behavior in thin-layer chromatography, gas-liquid chromatography, and liquid secondary ion mass spectroscopy. It was postulated that this substance was a precursor of V6 (SB1a) and V5 (Gg4Cer II3-sulfate, IV3-NeuAc) and to date, its presence has not been demonstrated in nature. Anotherm inor component V9 was identifieda s glucosyl ceramide sulfate based on itsm igration in thin-layer chromatography and gas-liquid chromatography. This renal cell line was shown to be an excellent model for studying the metabolism and function of sulfoglycolipids.
