Sphingosine synthesis
WebSep 7, 2024 · Ceramide is composed of sphingosine, an 18-carbon long-chain alcohol, linked to fatty acids via an amide bond, and it is known as a precursor of complex sphingolipids. Additionally, ceramides possess hydrocarbon chains of specific length in different species and tissues, and in yeast, mainly 26-carbon ceramides are being synthesized [ [ 4] ].

Second, the de novo pathway creates ceramide from less complex molecules. Third, in the "salvage" pathway, sphingolipids that are broken down into sphingosine are reused by reacylation to form ceramide.
