C16 Ceramide-d7 is intended for use as an internal standard for the quantification of C16 ceramide by GC- or LC-MS. C16 Ceramide is an endogenous ceramide, generated by ceramide synthase 6 (CerS6), that acts as a lipid second messenger to regulate apoptosis and stress signaling.[1] Accumulation of C16 ceramide through PPMP (30 μM) or MAPP (50 μM) treatment or from addition of 100 μM synthetic C16 ceramide induces apoptosis in neutrophil cultures via caspase-3 activation.[2]
