C24 Ceramide-1-Phosphate (d18:1/24:0) or N-lignoceroyl-ceramide-1-phosphate (ammonium salt) has been used as a standard to quantify ceramide content in muscle tissue samples using high-performance liquid chromatography/tandem mass spectrometry (LC/MS2).

Ceramide 1-phosphate (C1P) is a mitogenic agentwhich has antiapoptotic and prosurvival activities. It negatively regulates tumor necrosis factor-α (TNFα) production stimulated by lipopolysaccharide. C1P also mediates inflammatory response and aids in phagocytosis. It is considered as a second lipid messenger of agonist-stimulated sphingomyelin metabolism.
