WebCeramides are the basic structural units of all sphingolipids, and are formed through the union of a very long-chain fatty acids with sphingosine. Sphingomyelins are the only phospholipids that do not contain a glycerol backbone. Cerebrosides are formed through linkage of either glucose or galactose to the C1 of ceramide. Gangliosides have at least three sugars, one of which must be sialic acid. Inositol -containing ceramides, which are derived from phytoceramide, are produced in yeast. These include inositol phosphorylceramide, mannose inositol phosphorylceramide, and mannose diinositol phosphorylceramide.
