Metabolite Identification
Common NameSM(d18:0/18:1(9Z))
DescriptionSM(D18:0/18:1(9Z)), also known as C18:1DH sphingomyelin, 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. Thus, SM(D18:0/18:1(9Z)) is considered to be a phosphosphingolipid lipid molecule. SM(D18:0/18:1(9Z)) is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
