NEUTRAL GLYCEROGLUCOLIPIDS OF ALVEOLAR LAVAGE FROM RABBIT

Three individual glycolipids have been isolated from the neutral lipid fraction of rabbit alveolar lavage. All three glycolipids contained glucose, glyceryl monoethers and fatty acids, and differed from each other primarily with respect to the number of glucose residues. The structures of these glycolipids were identified by mild alkaline methanolysis, oxidation with periodate and CrO3, and methylation studies, as: Glc(α1 → 3)-1,(3)-O-alkyl-2-O-acylglycerol, Glc(α1 → 6)Glc(α1 → 6)Glc(α1 → 6)Glc-(α1 → 6)Glc(α1 → 3)-1,(3)-O-alkyl-2-O-acylglycerol, and Glc(α1 → 6)Glc(α1 → 6)Glc-(α1 → 6)Glc(α1 → 6)Glc(α1 → 6)Glc(α1 → 3)-1,(3)-O-alkyl-2-O-acylglycerol. © 1979.
