Sphingomyelin is a natural sphingolipid that existed in animal cell membranes. It implicates the regulation of transmembrane signaling.

C16 Sphingomyelin (d18:1/16:0) (N-Palmitoyl-D-sphingomyelin) is a phospholipid analog of phospholipid bilayer membranes, which can be used to study biofilm activity.

13C C16 Sphingomyelin (D18:1/16:0) is an isotopically enriched form of C16 sphingomyelin with carbon-13 occurring on the fatty acid portion. It is intended for use as an internal standard for the quantification of C16 sphingomyelin by GC- or LC-MS. C16 Sphingomyelin is a form of sphingomyelin containing palmitate (16:0) at the variable acylation position. It is the most common form of sphingomyelin found in eggs and is less abundant in the brain and in milk. C16 Sphingomyelin interacts with cholesterol in ordered lipid domains (lipid rafts). Sphingomyelinases remove phosphorylcholine from C16 sphingomyelin to produce C16 ceramide. While ceramides commonly induce apoptosis, ceramides with different fatty acid chain lengths might direct distinct functions and, in some cases, reduce apoptosis.

C20 Sphingomyelin is a naturally occurring sphingolipid. Levels of C20 sphingomyelin are upregulated in the hippocampus of rats with diabetes induced by streptozotocin and in human plasma, where it is positively correlated with insulin resistance in obese humans. C20 sphingomyelin is also upregulated in the liver of a mouse model of Niemann-Pick type C1 disease [a neurodegenerative cholesterol-sphingolipid lysosomal storage disorder]. The plasma concentration of C20 sphingomyelin is decreased in men with prostate cancer.

Sphingomyelin (chicken egg) (SMs (chicken egg)) is a sphingolipid derived from eggs and is a major component of the plasma membrane.Sphingomyelin (chicken egg) has been implicated in signaling in the body.

Lysosphingomyelin is an endogenous bioactive sphingolipid and a constituent of lipoproteins.1,2It is produced by the removal of the acyl group from sphingomyelin by a deacylase and acts as a precursor in the biosynthesis of sphingosine-1-phosphate .

Sphingomyelins (SMs) are bioactive sphingolipids found in mammalian cell membranes.1SMs make up 2-15% of the total organ phospholipid population but are found at higher concentrations in the brain and myelin sheaths surrounding peripheral nerves. They interact with cholesterol to control its distribution within cellular membranes and maintain cholesterol homeostasis in cells. SMs undergo hydrolysis by sphingomyelinase to form ceramides, which are sphingolipid mediators of intracellular signaling.2This product is a mixture of SMs, with variable fatty acyl chain lengths, isolated from buttermilk.

Sphingomyelins are complex membrane lipids composed of phosphorylcholine, sphingosine, and an acylated group, such as a fatty acid. Lysosphingomyelin is a naturally-occurring lipid which is produced by the removal of the acylated group of sphingomyelin by a deacylase. Lysosphingomyelin may, in turn, serve as a substrate for autotaxin, which removes choline to produce sphingosine-1-phosphate. The receptors and signaling pathways that are activated by lyso-sphingosine are diverse and vary between cell types. Lysosphingomyelin occurs naturally in plasma, is a constituent of lipoproteins, and is increased in some diseases, including dermatitis and Niemann-Pick disease.
