Partial characterization of glyceroglucolipids from human saliva

Glycolipids of human saliva have been isolated and partially characterized. The neutral glycolipids consisted of six compounds, composed of glucose, glyceryl ethers and fatty acids, and differed from each other primarily with respect to the number of glucose residues. The major acidic glycolipid contained glucose, glyceryl ethers, fatty acids and sulfate. Based on the data of chemical analyses we propose that the acidic glycolipid is a 1-0-alkyl-2-0-acylglycerol triglucoside sulfate and that the neutral glycolipids are mono-, di-, tri-, hexa- and octaglucoside derivatives of 1-0-alkyl-2-0-acylglycerol.
