Ceramide 1-phosphate is a bioactive lipid and one of the key components of sphingolipids. Ceramide 1-phosphate playing diverse roles in cellular behaviors such as cell differentiation, migration, proliferation and death[1].

ChEBI: N-octadecanoylsphingosine 1-phosphate is a ceramide 1-phosphate that is the N-octadecananoyl (stearoyl) derivative of sphingosine. It is functionally related to a sphingosine and an octadecanoic acid. It is a conjugate acid of a N-octadecanoylsphingosine 1-phosphate(2-).

Putative second messenger of agonist-stimulated sphingomyelin metabolism; may participate in cell regulation and transmembrane signaling.
