Ceramides (N-acylsphingosine) are one of the hydrolysis byproducts of sphingomyelin by the enzyme sphingomyelinase (sphingomyelin phosphorylcholine phosphohydrolase E.C.3.1.4.12) which has been identified in the subcellular fractions of human epidermis (PMID 25935) and many other tissues. They can also be synthesized from serine and palmitate in a de novo pathway and are regarded as important cellular signals for inducing apoptosis (PMID 14998372). Is key in the biosynthesis of glycosphingolipids and gangliosides.

N-[1-(Hydroxymethyl)-2-hydroxy-3-heptadecenyl]tetracosanamide
N-Lignoceroylsphingosine
A N-acylsphingosine in which the ceramide N-acyl group is specified as tetracosanoyl. Ceramide (N-acyl sphingosine) is known as an important precursor common to the biosynthesis of glycosphingolipids and sphingomyelin. Naturally occurring ceramide is composed of various molecular species resulting from a combination of C16 and 26 fatty acids and sphingosine (sphingenine). The N-acyl chain is thought to be mainly introduced by the acylation of sphinganine, and the resultant dihydroceramide (N-acyl sphinganine) is desaturated to form ceramide. The hydrolysis of sphingolipids also yields ceramide and may further lead to the generation of sphingosine and sphingosine phosphate. Recent studies have established the existence of a sphingomyelin cycle or a sphingomyelin pathway that operates in response to various agonists and stresses. Ceramide, is thought to act as a second messenger in the intracellular signaling pathway to apoptosis, cell cycle arrest, cell differentiation, cell propagation, or induction of cytokine synthesis.
