Assessment of Phospholipid Malabsorption by Quantification of Fecal Phospholipid
Journal of Pediatric Gastroenterology and Nutrition, 2004ABSTRACTObjectives:The standard methods for quantifying fat absorption involve extraction of fat from fecal samples with heptane, ether and ethanol. These solvents do not quantitatively recover phospholipids. Malabsorption of dietary and biliary phosphatidylcholine could potentially result in choline deficiency.

Phospholipid‐ phospholipid interaction in soybean oil
Journal of the American Oil Chemists' Society, 1981AbstractPhospholipid‐phospholipid interaction in soybean oil is described. Phosphatidylcholine was effectively removed from soybean oil by degumming (water hydration), whereas phosphatidylethanolamine and phosphatidic acid were hardly hydratable. However, the degree of their hydration increased in the presence of phosphatidylcholine.

A novel electron microscopy specimen protocol shows that the presumed phospholipid bilayer membrane ribbons that wind helically to form the cylinders known as "tubules" are actually flattened tubes. These flattened tubes are alternatively found with a helical twist about the tube's long axis or occasionally flat with no winding or twist.

PHOSPHOLIPIDS. PHYSICOCHEMICAL PROPERTIES OF PHOSPHOLIPIDS
The article discusses the composition and physical and chemical properties of phospholipids and the study of the chemical composition of phospholipids. It also discusses the development of methods for identifying and establishing the chemical composition of phospholipids.Tashmukhamedova, Shohista +1 more

Phospholipids in parasitic protozoa
Molecular and Biochemical Parasitology, 2003Parasitic protozoa are surrounded by membrane structures that have a different lipid and protein composition relative to membranes of the host. The parasite membranes are essential structurally and also for parasite specific processes, like host cell invasion, nutrient acquisition or protection against the host immune system. Furthermore, intracellular

Binding of Serpins to Immobilized Phospholipids and Phospholipids in Suspension
2018Binding of serine protease inhibitors (serpins) to nonprotein ligands such as glycosaminoglycans or phospholipids has been shown to modify their inhibitory activity and-at least in the case of SERPINA5-to mediate serpin internalization into cells. Also phospholipid functions may be altered when bound to serpins or other proteins.By interacting with ...

Hyaluronan–Phospholipid Interactions
Journal of Structural Biology, 1997Hyaluronan-phospholipid interactions have been studied in vitro by negative staining and rotary shadowing electron microscopy. Hyaluronan (HA) molecules of different molecular weights (around 170,000; 740,000, and 1.9 x 10(6) Da) were added to phospholipid suspensions (DPPC or egg lecithin) that were in the form of either unilamellar particles or ...

AbstractIt has been demonstrated that in hepatocyte nuclei the chromatin phospholipid fraction is localized near the RNA in decondensed chromatin. The aim of the present study was to see if there is any linkage between phospholipids and other nuclear components.

[23] Extraction of phospholipids and analysis of phospholipid molecular species
1990Publisher Summary The chapter presents a discussion on extraction of phospholipids and analysis of phospholipid molecular species. The phospholipids (PLs) are a family of molecules that, with the exception of sphingomyelin (SM), are characterized by the presence of a phosphate group esterified to the sn -3 position of glycerol and 1 (lyso-PLs) to 4 (
