Sphingolipids are ubiquitous in all eukaryotic organisms. Various physiological functions of
dietary sphingolipids, such as preventing colon cancer and improving the skin barrier
function, have been recently reported. One of the common sphingolipids used as a foodstuff
is glucosylceramide from plant sources, which is composed of sphingoid bases distinct from
those of mammals. However, the fate of dietary sphingolipids derived from plants is still not
understood. In this study, we investigated the absorption of maize glucosylceramide in the …
