Abstract/OtherAbstract:
Total non-acid glycolipid fractions have been isolated from GMK AH-1 cells grown in fetal calf serum and in horse serum. For comparison, glycolipids were also prepared from green monkey (Cercopithecus aetiops) kidney and from fetal calf serum. The major glycolipids from GMK AH-1 cells grown in fetal calf serum were isolated by silicic acid column chromatography and preparative thin-layer chromatography. These fractions were characterized mainly by thin-layer chromatography, mass spectrometry and gas chromatography. The structures of the glycolipids isolated were proposed as: Glc1 leads to 1Cer, Gal1 leads to 1Cer, Gal1 leads to 4Glc1 leads to 1Cer, Gal1 leads to 4Gal1 leads to 4Glc1 leads to 1Cer, GalNAcl leads to 3Gal1 leads to 4Gal1 leads 4Glc1 leads to 1Cer. In addition, a novel pentaglycosylceramide with the probable structure Ga1 beta 1 leads to 3GalNAc beta 1 leads to Gal alpha 1 leads to 4Gal beta 1 leads to 4Glc beta 1 leads to 1Cer was also present. THe ceramides contained mainly dihydroxy 18:1 long-chain base in combination with non-hydroxy 16:0-24:0 fatty acids. Small amounts of trihydroxy 18:0 long-chain base and hydroxy 22:0-24:0 fatty acids were also present in the mono- and diglycosylceramide fractions. The glycolipid patterns of GMK AH-1 cells grown in fetal calf serum or horse serum were identical. The pentaglycosylceramide present in the cultured cells could not be detected with certainty in the kidney tissue. The uptake of this glycolipid from the culture medium is unlikely as it seems to be lacking in calf serum.
