1-Myristoyl-2-hydroxy-sn-glycero-3-PE is a lysophospholipid with a phosphoethanolamine head and a myristoyl tail. The free amine group can conjugate with NHS active ester or coupled with carboxylic acid in the presence of a coupling agent. It also induces transient increases in intracellular calcium in PC12 cells. Serum levels of 1-Myristoyl-2-hydroxy-sn-glycero-3-phosphoethanolamine are elevated in patients with malignant breast cancer compared to healthy controls.
