Matched Description: , sulfagalactosylceramides, lactosylceramides, and various other ceramides. The core of a sphingolipid is the … substrates for this reaction are palmitoyl-CoA and serine. Next, 3-keto-dihydrosphingosine is reduced … metabolites to ceramide. The complex glycosphingolipids are hydrolyzed to glucosylceramide and … galactosylceramide. These lipids are then hydrolyzed by beta-glucosidases and beta-galactosidases to … ceramides and phosphocholine. The only route by which sphingolipids are converted into non-sphingolipids is
