      Ceramides, such as Cer(d18:1/16:0) (systematic name: N-(hexadecanoyl)-sphing-4-enine) are a class of sphingolipids composed of the long-chain base sphingosine attached to a fatty acid via an N-acyl linkage. Ceramides are found in high concentrations within the cell membrane of cells. De novo synthesis of ceramide occurs in the endoplasmic reticulum. Ceramide is subsequently transported to the Golgi apparatus by either vesicular trafficking or the ceramide transfer protein CERT. Once in the Golgi apparatus, ceramide can be further metabolized to other sphingolipids, such as sphingomyelin (a key component of cell membranes) and the complex glycosphingolipids.
