Description | SM(d18:0/20:2(11Z,14Z)) (d18:0/20:2(11Z,14Z)) or SM(d18:0/20:2(11Z,14Z))is a type of sphingolipid found in animal cell membranes, especially in the membranous myelin sheath which surrounds some nerve cell axons. It usually consists of phosphorylcholine and ceramide. In humans, SM(d18:0/20:2(11Z,14Z)) is the only membrane phospholipid not derived from glycerol. Like all sphingolipids, SPH has a ceramide core (sphingosine bonded to a fatty acid via an amide linkage). In addition it contains one polar head group, which is either phosphocholine or phosphoethanolamine. The plasma membrane of cells is highly enriched in SM(d18:0/20:2(11Z,14Z)) and is considered largely to be found in the exoplasmic leaflet of the cell membrane. However, there is some evidence that there may also be a SM(d18:0/20:2(11Z,14Z)) pool in the inner leaflet of the membrane. Moreover, neutral sphingomyelinase-2 - an enzyme that breaks down SM(d18:0/20:2(11Z,14Z)) into ceramide has been found to localise exclusively to the inner leaflet further suggesting that there may be SM(d18:0/20:2(11Z,14Z)) present there. SM(d18:0/20:2(11Z,14Z)) can accumulate in a rare hereditary disease called Niemann-Pick Disease, types A and B. Niemann-Pick disease is a genetically-inherited disease caused by a deficiency in the enzyme Sphingomyelinase, which causes the accumulation of SM(d18:0/20:2(11Z,14Z)) in spleen, liver, lungs, bone marrow, and the brain, causing irreversible neurological damage. SMs play a role in signal transduction.
Sphingomyelins are synthesized by the transfer of phosphorylcholine from phosphatidylcholine to a ceramide in a reaction catalyzed by SM(d18:0/20:2(11Z,14Z)) synthase. |

Chemical Taxonomy |
---|
Description | belongs to the class of organic compounds known as phosphosphingolipids. These are sphingolipids with a structure based on a sphingoid base that is attached to a phosphate head group. They differ from phosphonospingolipids which have a phosphonate head group. |
