Figure 4From: The endocannabinoid anandamide is a precursor for the signaling lipid N-arachidonoyl glycine by two distinct pathwaysMass spectrometric product ion scans of synthesized standards and RAW 264.7 lipid extracts. The numbers above the peaks are the calculated centroid mass. A) Positive ion mode product ion scan of the mass [348.3]+ of the synthesized standard of non-deuterium labeled N-arachidonoyl ethanolamine (D0AEA). B) Positive ion mode product ion scans of the mass [352.3]+ of the synthesized standard of deuterium-labeled AEA (D4AEA). C) Positive ion mode product ion scan of the mass [362.3]+ of the synthesized standard of non-deuterium labeled NAGly (D0NAGly). D) Positive ion mode product ion scan of the mass [364.3]+ of the RAW 264.7 cell extract that was incubated with D4AEA.Back to article page
