1-Palmitoyl-2-hydroxy-sn-glycero-3-PE is a naturally-occurring lysophospholipid. [1] It inhibits the growth of L. donovani promastigotes (GIC50 = 8 uM). [2]1-Palmitoyl-2-hydroxy-sn-glycero-3-PE serum levels are decreased in a mouse model of alcohol-induced liver injury and in a hepatocellular carcinoma mouse xenograft model. [3] Human serum levels are also decreased immediately and 14 hours following an exercise regimen of 2.5 hours of running for three days. [1]1-Palmitoyl-2-hydroxy-sn-glycero-3-PE has been used as an internal standard for the quantification of saturated lysophosphoethanolamines. [4]
1,2-Dipalmitoyl-sn-glycero-3-PE-N-(cap biotin) is a biotinylated phospholipid. It has been used in PEGylated polyamidoamine-dendrimer-conjugated supported lipid bilayers (SLB) to isolate circulating tumor cells and tumor cell microembolis from patient-derived blood by antibody-coated microfluidics. [1] It has also been used as a component of SLBs to detect protein-ligand binding with ortho-conjugated Texas Red DHPE. [2] In addition, 1,2-dipalmitoyl-sn-glycero-3-PE-N-(cap biotin) has been used in SLBs partitioned into nanowells to create DNA curtains, which can be used as a high-throughput tool for detection of protein-DNA interactions at the single molecule level.[3]
1-Myristoyl-2-hydroxy-sn-glycero-3-PE is a naturally occurring lysophospholipid. It induces transient increases in intracellular calcium in PC12 cells. Serum levels of 1-myristoyl-2-hydroxy-sn-glycero-3-PE are elevated in patients with malignant breast cancer compared to healthy controls.
1-Stearoyl-2-15(S)-HETE-sn-glycero-3-PE is a phospholipid that contains stearic acid at the sn-1 position and 15(S)-HETE at the sn-2 position. It is formed in human peripheral monocytes activated by the calcium ionophore A23187 by direct oxidation of 1-stearoyl-2-arachidonoyl-sn-glycero-3-PE by 15-LO. Phosphoethanolamine (PE) HETEs (PE-HETEs), including 1-stearoyl-2-15(S)-HETE-sn-glycero-3-PE, are the main source of esterified HETE in ionophore-activated monocytes.
1-Stearoyl-2-15(S)-HpETE-sn-glycero-3-PE is a phospholipid that contains stearic acid at the sn-1 position and 15(S)-HpETE at the sn-2 position. It is produced via oxidation of 1-stearoyl-2-arachidonoyl-sn-glycero-3-PE by 15-lipoxygenase (15-LO). 1-Stearoyl-2-15(S)-HpETE-sn-glycero-3-PE (0.6 and 0.9 μM) increases ferroptotic cell death in wild-type and Acsl4 knockout Pfa1 mouse embryonic fibroblasts (MEFs) treated with the GPX4 inhibitor RSL3.
Phosphatidylethanolamines are important components of cell membranes and biochemical pathways of fatty acid synthesis. 1-Palmitoyl-2-linoleoyl PE (PLPE) is one of the many phosphatidylethanolamines that may be present in cellular membranes. It has been used in studies involving the biosynthesis of anandamide via the phospholipase A2 (PLA2) and lysoPLD pathways. PLPE can also be used as a specific substrate to assess the activity of sPLA2-IIA in the presence of other phospholipids.
1,3-Dipalmitoyl glycero-2-phosphatidylethanolamine is a phospholipid incorporating saturated long-chain (16:0) stearic acid at the sn-1 and sn-3 positions, with phosphatidylethanolamine (PE) at the sn-2 position. Phosphatidylethanolamines, critical components of biological membranes, play essential structural and functional roles. Various PE types are instrumental in forming micelles, liposomes, and other synthetic membranes.
1-Palmitoyl-2-docosahexaenoyl-sn-glycero-3-PE, a phospholipid comprising palmitic acid (at the sn-1 position) and docosahexaenoic acid (at the sn-2 position), is present in the nucleus of mouse liver but absent from mitochondria. Notably, its levels in pre-term infant plasma are lower compared to those in maternal or fetal plasma.
1-Palmitoyl-2-arachidonoyl-sn-glycero-3-PE, a phospholipid comprising palmitic acid and arachidonic acid at the sn-1 and sn-2 positions respectively, is identified in egg yolk and isolated rat retina.
1-1(Z)-Hexadecenyl-2-palmitoyl-sn-glycero-3-PE, a plasmalogen, incorporates 1(Z)-hexadecenoic acid and palmitic acid at the sn-1 and sn-2 positions, respectively.
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.
