Opis ogólny

Sphingomyelin (SM) is a principal sphingolipid in mammalian cell membranes. Its biological functions have been studied.

Zastosowanie

Sphingomyelin is suitable for use:
  • in the preparation of standard during the enzymatic measurement of plasma sphingomyelin levels
  • to study the binding of Vascular Anticoagulant α (VAC α) to planar phospholipid bilayers
  • to perform fluorescence polarization of PC16 (N-[α-N-palmitoyl-ε-N-(4-nitrobenz-2-oxa-1,3-diazole)-L-lysine]-2-aminoethanol-N- (trimethylaminoethanol) phosphate) in dispersions of co-sonicated lecithin and sphingomyelin
  • for reconstitution of viral ion channel protein M2 into liposomes
  • as a standard sample to define spectral fingerproint using Time-of-flight secondary ion mass spectrometry (ToF-SIMS)
  • to evaluate the contribution of various phospholipids to the formation of foam in the amniotic fluid

Działania biochem./fizjol.

Sphingomyelin is the second most abundant lipid and major sphingolipid component of HDL and the plasma membrane. It forms cholesterol-enriched lipid rafts. It has a key role in the availability of plasma membrane-free cholesterol.

Jakość

Contains primarily palmitic acid.

Clinical chemistry, 33(7), 1177-1184 (1987-07-01)
The mechanism of a new fluorescence polarization method for measuring phospholipid in amniotic fluid is described. The fluorescence polarization of a surfactant fluorescent dye solubilized in amniotic fluid correlates significantly with the L/S ratio. Model studies indicate that this results
D E Freer et al.
Clinical chemistry, 24(11), 1980-1984 (1978-11-01)
We evaluated the relative contributions of various phospholipids to the formation of foam in the amniotic fluid "foam stability test", by use of an artificial system of saline, ethanol, and dipalmitoyl 3-sn-phosphatidylcholine to determine the relationship between dipalmitoyl 3-sn-phosphatidylcholine concentration

Journal of lipid research, 47(3), 673-676 (2005-12-24)
Sphingomyelin (SM) and phosphatidylcholine (PC) are two major phospholipids on plasma lipoproteins. Their concentration is classically measured by lipid extraction, thin-layer chromatography, and phosphate determination on separated SM or PC spots. Here, we describe two rapid, specific, and sensitive enzymatic

Vascular anticoagulant alpha (VAC alpha, annexin V) is a member of the family of calcium and phospholipid binding proteins, the annexins. The binding properties of VAC alpha to phospholipid bilayers were studied by ellipsometry. Adsorption was calcium-dependent and completely reversible
