title: New types of gangliosides in starfish with sialic acid residues in the inner part of their carbohydrate chains.
abstract: Three gangliosides were isolated from the starfish by Folch's partition, dialysis, silicic acid column chromatography, Iatrobead column chromatography and preparative thin-layer chromatography. Partial acid hydrolysis of the three lipids in 0.1 N HCl at 80 degrees for 90 min liberated all the lactosyl ceramide and water-soluble degradation products, but no sialic acid. Gas-liquid chromatography of the trimethylsilylated methyl glycosides of the water-soluble products demonstrated the presence of arabinose in addition to the usual sugar units of gangliosides.
