Web18:1 DGPP dioleoylglycerol pyrophosphate (ammonium salt) Diacylglycerol pyrophosphate (DGPP), involved in a novel signaling pathway, has been found in plants, Saccharomyces cerevisiae, and Escherichia coli and macrophage-activating factor, and suggests a potential role for this compound in triggering homeostatic cellular responses. Webacid (PA), diacylglycerol (DAG), lysophospholipids, or free fatty acids, may be attributed to the action of multiple phospholipases (Lee et al. 1997, Ryu and Wang 1998, van der Luit et al. 2000, Wang 2000).
