General description
Lysophosphatidic acid (LPA) is a class of phospholipids, which is water-soluble. It has a glycerol backbone attached via a phosphate group, an aliphatic chain and a hydroxyl group. The aliphatic chain is linked to either sn-1 or sn-2 position and the phosphate group is connected to the sn-3 position. The hydroxyl group is linked to the remaining sn-1 or sn-2 position.
Application
C18 LPA or 1-O-octadecyl-2-hydroxy-sn-glycero-3-phosphate may be used:
- to study its effects on Yes-associated protein (YAP) phosphorylation
- as a standard for the quantification of lysophosphatidic acid (LPA) compounds in proton samples using reversed-phase ultra-performance liquid chromatography-tandem mass spectrometer (UPLC-MS/MS)
- as a substrate to investigate the phosphatase activity of soluble epoxide hydrolase (sEH) towards LPA compounds
Biochem/physiol Actions
Lysophosphatidic acid (LPA) is a signaling molecule and alters various cellular responses through G protein-coupled receptors (GPCRs). It stimulates smooth muscle contraction, cytoskeleton rearrangement and chemotaxis. LPA is also involved in inducing neurotransmitter release, cell proliferation, platelet aggregation and Ca2+ mobilization. Increased levels of LPA in human plasma leads to ovarian cancer and atherosclerosis. LPA acts as a potential biomarker for ovarian cancer.

Soluble epoxide hydrolase (sEH) is a bifunctional enzyme that has a C-terminus epoxide hydrolase domain and an N-terminus phosphatase domain. The endogenous substrates of epoxide hydrolase are known to be epoxyeicosatrienoic acids, but the endogenous substrates of the phosphatase activity

Lysophosphatidic acid (LPA) is a ligand for LPA(1-3) of the endothelial differentiation gene family G-protein-coupled receptors, and LPA(4-8) is related to the purinergic family G-protein-coupled receptor. Because the structure-activity relationship (SAR) of GPR92/LPA(5) is limited and whether LPA is its
