A substance which occurs widely in brain and nervous tissue, consisting of complex phosphoryl derivatives of sphingosine and choline.
- ‘Cholesterol and sphingomyelin are thought to be the principal components of lipid rafts in cell and model membranes.’
- ‘In this study, we have examined how the headgroup size and properties affect the membrane properties of sphingomyelin and interactions with cholesterol.’
- ‘In contrast, choline is essentially derived from the circulation, and only negligible amounts are incorporated into other lipids, such as sphingomyelin.’
- ‘The most important sphingolipids are sphingomyelins.’
- ‘In many cases, properties attributed to sphingomyelins may simply be due to chain length and unsaturation.’
