   sphingomyelin
   A sphingolipid in which the head group is phosphoryl choline. A close analogue of phosphatidyl choline. In many cells the concentration of sphingomyelin and phosphatidyl choline in the plasma membrane seems to bear a reciprocal relationship.

   sphingomyelin
   (from the article `sphingolipid`) Sphingomyelins, which are the only phosphorus-containing sphingolipids, are most abundant in nervous tissue, but they also occur in the blood. In bilayers many glycerophospholipids as well as sphingomyelin (discussed below) can be in either one of two states, gel or...

   Sphingomyelin
   Sphingomyelin (SPH, ˌsfɪŋɡoˈmaɪəlɪn) is a type of sphingolipid found in animal cell membranes, especially in the membranous myelin sheath that surrounds some nerve cell axons. It usually consists of phosphorylcholine and ceramide. In humans, SPH represents ~85% of all sphingolipids. ==Compo...
