There are several ways to generate ceramide in mammalian cells (Figure 1): hydrolysis of sphingomyelin, de novo synthesis from palmitoyl-CoA and serine, catabolism of glucosylceramide and galactosylceramide, synthesis from sphingosine and fatty acid, and dephosphorylation of ceramide-1-phosphate.
SM can also be used to synthesize PC as the donor of PPC that is added to diacylglycerol by the reverse sphingomyelin synthase (RSM-synthase) [3].

In both [N.sub.2] and air APPJ treatments, peaks at 3.26 and 3.65 ppm are significantly reduced, which represent [sup.1]H at the choline [-N[(C[H.sub.3]).sub.3]] of phosphatidylcholine or sphingomyelin. In contrast, peaks at 3.16 ppm are significantly enhanced after only [N.sub.2] APPJ treatments, which represents [-C[H.sub.2]N[H.sup.+.sub.3]] of phosphatidylethanolamine.
