1-Palmitoyl-d9-2-hydroxy-sn-glycero-3-PE serves as an internal standard for quantifying 1-palmitoyl-2-hydroxy-sn-glycero-3-PE, a lysophospholipid naturally found to inhibit L. donovani promastigotes growth (GI50= 8 µM). Its levels are reduced in mice after alcohol-induced liver damage, in hepatocellular carcinoma mouse xenografts, and in humans following a rigorous three-day exercise regimen of 2.5 hours running daily and 14 hours post-regimen. This compound is also applied in measuring saturated lysophosphoethanolamines, highlighting its broad utility in biochemical research and disease model studies.

1-Palmitoyl-d9-2-palmitoyl-sn-glycero-3-PE serves as an internal standard for the quantification of 1,2-dipalmitoyl-sn-glycero-3-PE (1,2-DPPE) using GC- or LC-MS. 1,2-DPPE, a prevalent PE (phospholipid), contains C16:0 fatty acids at the sn-1 and sn-2 positions and is essential in the inner plasma membrane leaflet. This compound forms a condensed lipid monolayer with cholesterol through tight hydrogen bonding between 1,2-DPPE headgroups, enhancing membrane fluidity to support transport and signaling.

1-1(Z)-Hexadecenyl-2-palmitoyl-d9-sn-glycero-3-PE serves as an internal standard for quantitating 1-1(Z)-hexadecenyl-2-palmitoyl-sn-glycero-3-PE, which is a plasmalogen incorporating 1(Z)-hexadecanoic acid and palmitic acid at the sn-1 and sn-2 positions respectively, in analyses performed using GC- or LC-MS.
