Molecular packing in sphingomyelin bilayers and sphingomyelin/phospholid mixtures
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2003The molecular packing properties of sphingomyelin (SM) from egg yolk were studied. The influence of the spontaneous curvature of SM on the phase behaviour of SM/dodecane/water systems was investigated. A comparison was made to a previous study by Lindblom et al. (Liq. Cryst. 3 (1988) 783), of the phase behaviour of dipalmitoylphosphatidylcholine (DPPC)/

AN investigation of marine phospholipids in this laboratory necessitated the determination of Sphingomyelin. Sphingomyelin is frequently estimated by determining sphingosine according to the method of McKibbin and Taylor1. This method consists of the separation of sphingosine from other nitrogenous bases by extraction from an aqueous acid solution with

Regulation of sphingomyelin metabolism
Pharmacological Reports, 2016Sphingolipids (SFs) represent a large class of lipids playing diverse functions in a vast number of physiological and pathological processes. Sphingomyelin (SM) is the most abundant SF in the cell, with ubiquitous distribution within mammalian tissues, and particularly high levels in the Central Nervous System (CNS).

Sphingomyelin synthases and testicular function
Expert Review of Endocrinology & Metabolism, 2008Sphingomyelin synthase (SMS) is a cellular enzyme that catalyzes de novo synthesis of sphingomyelin (SM), which is a vital lipid component of cell membranes. Both members of the SMS family, SMS1 and SMS2, are found in mammalian testes and they are located in distinctive subcellular compartments, with SMS1 in the Golgi apparatus and SMS2 in the plasma ...

Biological functions of sphingomyelins
Progress in Lipid Research, 2013Sphingomyelin (SM) is a dominant sphingolipid in membranes of mammalian cells and this lipid class is specifically enriched in the plasma membrane, the endocytic recycling compartment, and the trans Golgi network. The distribution of SM and cholesterol among cellular compartments correlate.

Lateral diffusion in sphingomyelin bilayers
Magnetic Resonance in Chemistry, 2010AbstractSphingomyelin (SM) is an important lipid of eukaryotic cellular membranes and neuronal tissues. We studied lateral diffusion in macroscopically oriented bilayers of synthetic palmitoylsphingomyelin (PSM) and natural sphingomyelins of egg yolk (eSM), bovine brain (bSM) and bovine milk (mSM) by pulsed field gradient NMR (PFG NMR) in the ...

Structural diversity of sphingomyelin microdomains
Ultramicroscopy, 2004In cells plasma membrane, sphingomyelin (SM) plays a key role in the formation of a category of lipid microdomains enriched in cholesterol (Chl) often referred to as rafts. Atomic force microscopy (AFM) was used to analyze the mesoscopic topography of enriched SM microdomains in supported bilayers made of SM/dioleoylphosphatidylcholine (SM/DOPC) and SM/

Sphingolipids play important roles in apoptosis, differentiation, senescence, proliferation, and inflammation. The sphingomyelin (SM) cycle, with the key components of SM, sphingomyelinase (SMase) and ceramide, has received substantial attention to date because of its role in cell signaling.

Sphingomyelin breakdown and cell fate
Trends in Biochemical Sciences, 1996A growing number of cell-surface receptors are now being shown to generate signals that trigger the hydrolysis of sphingomyelin to release diffusible ceramides. Ceramides have been implicated as key mediators in signaling pathways, with outcomes as diverse as cell proliferation, differentiation, growth arrest and apoptosis. The response depends on cell
