Glycolipids of rat small intestine. Characterization of a novel blood group H-active triglycosylceramide.
A novel blood group H-active triglycosylceramide has been isolated from rat small intestine. It was present exclusively in the epithelial cells. The structure was established by mass spectrometry, NMR spectroscopy and degradative methods to the Fucp alpha 1 leads to 2Galp beta 1 leads to 4Glcp beta 1 leads to 1Cer. The lipophilic part was made up of mainly trihydroxy base (phytosphingosine) and 16 : 0--24 : 0 fatty acids.
