General description

Lysophosphatidic acid (1- or 2-acyl-lysophosphatidic acid/LPA), a bioactive phospholipid is seen at a low level in plasma (~100nM). It is usually formed during the synthesis of phospholipid of cell membranes. It is produced by various cells like, activated platelets, epithelial cells, leukocytes, neuronal cells and tumor cells. 18:0 Lyso PA has stearic acid at sn-1 and a hydroxyl group at sn-2 position.

Application

18:0 Lyso PA is suitable for use:
  • to determine the extraction recovery of LPA at neutral pH and acidic pH by chromatographic method
  • to use as internal standard to study the role of intestinally derived lysophosphatidic acid in dyslipidemia and atherosclerosis
  • to investigate its effects on clathrin?dependent endocytosis

Biochem/physiol Actions

Lysophosphatidic acid (1- or 2-acyl-lysophosphatidic acid/LPA) modulates cell motility, proliferation, invasion, survival and production of growth factors via G protein-coupled receptor (GPCR).
