Background:

Production of ceramide occurs upon hydrolysis of sphingomyelin by a specific isoform of PLC, appropriately named sphingomyelinase.[1] C24:1 Ceramide (d18:1/24:1(15Z)) is one of the most abundant naturally occurring ceramides.[2],[3],[4] Ceramides mediate many diverse biological activities, as has been demonstrated in studies utilizing cell-permeable ceramide analogs. A few of the processes regulated by ceramides include apoptosis, cell differentiation, proliferation of smooth muscle cells, and inhibition of the mitochondrial respiratory chain.[5,][6],[7]
