Abstract
Sphingolipids, and their metabolizing enzymes, have emerged as significant players in cell signaling and biology. These bioactive lipids function not only as structural lipids in cell, but mediate significant biologic functions as well. Sphingolipid enzymes function in the intestinal lumen to degrade exogenous dietary sphingolipids and in the enterocytes themselves to generate endogenous sphingolipids. Among the most studied bioactive sphingolipids are ceramide, sphingosine, and sphingosine-1-phosphate. These sphingolipids and their synthetic enzymes have been extensively implicated in intestinal inflammation and tumorigenesis and will be the focus of this chapter.
