Title: Isolation and characterization of a heptaglycosylceramide from bovine erythrocyte membranes. Author: Chien JL, Li SC, Li YT. Journal: J Lipid Res; 1979 Jul; 20(5):669-73. PubMed ID: 490044. Abstract: A heptaglycosylceramide was isolated from bovine erythrocyte membranes. The structure was characterized to be Gal(alpha 1-3)Gal(beta 1-4)GlcNAc(beta1-3)Gal(beta 1-4)Glc-NAc(beta 1-4)al(beta 1-4)GlcCer. A hexaglycosylceramide that has the same sequence except for the terminal alpha-galactosyl unit has also been isolated. We have previously found that gangliosides isolated from bovine erythrocyte membranes contain a keratan sulfate type repeating unit --[3Gal(beta 1-4)-GlcNAc beta]--n. This study shows that the keratan sulfate type repeating unit is also present in the neutral glycosphingolipids of bovine erythrocyte membranes.[Abstract] [Full Text] [Related] [New Search]
