| Common Name | SM(d18:0/24:1(15Z)(OH)) |
|---|
| Description | SM(d18:0/24:1(15Z)(OH)), also known as C24:1-OH sphingomyelin or hydroxysphingomyeline C24:1, 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. Sphingomyelins are synthesized by the transfer of phosphorylcholine from phosphatidylcholine to a ceramide in a reaction catalyzed by SM(d18:0/24:1(15Z)(OH)) synthase. SM(d18:0/24:1(15Z)(OH)) is an extremely weak basic (essentially neutral) compound (based on its pKa). Moreover, neutral sphingomyelinase-2 - an enzyme that breaks down SM(d18:0/24:1(15Z)(OH)) into ceramide has been found to localise exclusively to the inner leaflet further suggesting that there may be SM(d18:0/24:1(15Z)(OH)) present there. Outside of the human body, SM(d18:0/24:1(15Z)(OH)) has been detected, but not quantified in, several different foods, such as cow milks, cow milks, cow milks, and cow milks. This could make SM(D18:0/24:1(15Z)(OH)) a potential biomarker for the consumption of these foods. In addition it contains one polar head group, which is either phosphocholine or phosphoethanolamine. SM(d18:0/24:1(15Z)(OH)) (d18:0/24:1(15Z)(OH))or SM(d18:0/24:1(15Z)(OH)) is a type of sphingolipid found in animal cell membranes, especially in the membranous myelin sheath which surrounds some nerve cell axons. SM(d18:0/24:1(15Z)(OH)) was first documented in 1994 (PMID: 8106344). SMs play a role in signal transduction (PMID: 9034165). |
