DOI: 10.1016/j.plipres.2013.05.001 Abstract Sphingomyelin (SM) is a dominant sphingolipid in membranes of mammalian cells and this lipid class is specifically enriched in the plasma membrane, the endocytic recycling compartment, and the trans Golgi network. What disease is characterized by deficient degridation of sphingomyelin? Disease at a Glance Summary Niemann-Pick disease is an inherited condition involving lipid metabolism, which is the breakdown, transport, and use of fats and cholesterol in the body. Hall, J.A. Hide. A group of phospholipids, found in brain, spinal cord, kidney, and egg yolk, containing 1-phosphocholine (choline O-phosphate) combined with a ceramide (a long-chain fatty acid linked to the nitrogen of a long-chain base, such as sphingosine). In sphingomyelin, the amino group of the sphingosine backbone is linked to a fatty acid by an amide bond. In types A and B, insufficient activity of an enzyme called sphingomyelinase causes the build up of toxic amounts of sphingomyelin, a fatty substance present in every cell of the body. intervene in numerous cell biological processes and signaling pathways and that deregulation is implicated in human diseases such as Gaucher disease and Parkinson's disease. SMSs was found associated with various diseases.

Acid sphingomyelinase deficiency (ASMD) is a rare lipid storage disorder with a genetic etiology. Sphingomyelin is the most abundant sphingolipid in animal cell membranes, localized to the outer membrane leaflet where it greatly contributes to the formation of specialized liquid-ordered domains called lipid rafts. Hydrolysis of membrane-embedded, inert sphingomyelin by stress responsive sphingomyelinases is a hallmark of adaptive responses and cellular repair. The ultimate biosynthesis of SM is catalyzed by two sphingomyelin synthases (SMSs) namely SMS1 and SMS2, which are selectively distributed in the trans-Golgi apparatus and the plasma membrane. Quantifying sphingomyelin (SM) species by infusion-based mass spectrometry (MS) is complicated by the presence of isobaric phosphatidylcholine (PC) species, which generate a common m/z 184 product ion in the presence of ammonium ions as a result of the phosphocholine headgroup. 2. 4. sphingomyelin: [ sfinggo-mi-lin ] a group of phospholipids that on hydrolysis yield phosphoric acid, choline, sphingosine, and a fatty acid.
