Interaction of glucagon with sphingomyelins
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1982Abstract In the presence of either egg or bovine brain sphingomyelin, the spectral properties of glucagon undergo changes which are similar to those which occur in the presence of synthetic phosphatidylcholines. The fluorescence emission spectra are blue shifted about 10 nm in the presence of lipid and the peptide acquires an increased helical ...

THE ISOLATION OF BEEF SPHINGOMYELINS
Canadian Journal of Biochemistry, 1964A method was developed for the quantitative isolation of tissue sphingomyelins. Total lipid extracts of tissues were subjected to selective hydrolysis to destroy ester phosphatides and plasmalogens. The water-soluble hydrolysis products were removed by solvent fractionation.

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).

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.

In this study, we examine the phase behavior as well as lateral diffusion and percolation in the region of coexisting gel and fluid phases in binary mixtures composed of dimyristoylphosphatidylcholine and one of two totally synthetic D-erythro-sphingomyelins (having either C16 or C24 acyl chains, both having similar gel to liquid-crystalline phase ...

Meconium has no lecithin or sphingomyelin but affects the lecithin/sphingomyelin ratio
American Journal of Obstetrics and Gynecology, 1998Although a few studies have evaluated the effect of meconium on the lecithin/sphingomyelin ratio for testing of fetal lung maturity, to date these studies have assessed only the lecithin-sphingomyelin ratio of amniotic fluid contaminated with meconium.

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.
