Barbiturate Interaction with Phosphatidylcholine [PDF]
A hydrogen-bonding interaction between phenobarbital or pentobarbital with phosphatidylcholine in chloroform is indicated by the effects of added phosphatidylcholine on the infrared and proton magnetic resonance spectra of these barbiturates. The nitrogenbound proton of the barbiturate and the orthophosphate moiety of the phosphatidylcholine molecule ...

Phosphatidylcholine synthesis in yeast.
The two pathways for the biosynthesis of phosphatidylcholine, by way of phosphocholine and by methylation of phosphatidylethanolamine, in wild-type yeast (Saccharomyces cerevisiae) and in the yeast mutant GL7 have been compared. The mutant requires for growth a sterol, unsaturated fatty acids, and methionine.

Miscibility of Sphingomyelins and Phosphatidylcholines in Unsaturated Phosphatidylcholine Bilayers [PDF]
Polyunsaturated phospholipids are common in biological membranes and affect the lateral structure of bilayers. We have examined how saturated sphingomyelin (SM; palmitoyl and stearoyl SM (PSM and SSM, respectively)) and phosphatidylcholine (PC; dipalmitoyl PC and 1-palmitoyl-2-stearoyl PC (DPPC and PSPC, respectively)) segregate laterally to form ...

Mucosal Protection by Phosphatidylcholine [PDF]
The colonic mucus serves a first barrier towards invasion of commensal bacteria in stools to prevent inflammation. One essential component of intestinal mucus is phosphatidylcholine (PC) which represents more than 90% of the phospholipids in mucus indicative for a selective transport of PC into this compartment. It is arranged in lamellar structures as

Digestion and Absorption of Milk Phospholipids in Newborns and Adults
Milk polar lipids provide choline, ethanolamine, and polyunsaturated fatty acids, which are needed for the growth and plasticity of the tissues in a suckling child.

Injecting phosphatidylcholine has been used in South America as a non-surgical treatment in body contouring. The objective of this study was to demonstrate the efficacy of injecting phosphatidylcholine in the reduction of localised fat deposits.

Phosphatidylcholine content in soybean: Genetic variability and the effect of growing year
Information on the genetic variability of phosphatidylcholine (PC) content in soybean (Glycine max L.) is scanty. In the present investigation, estimation of PC content in 408 soybean accessions from 15 countries revealed a range of 2.04-8.80 mg/g soy ...

Hemolysis of Rat Erythrocytes by Replacement of the Natural Phosphatidylcholine by Various Phosphatidylcholines [PDF]
Vesicles of a variety of types of phosphatidylcholine have been shown to be suitable donors of phosphatidylcholine to intact rat erythrocytes in the presence of a specific phosphatidylcholine exchange protein. Coincident with the progression of phosphatidylcholine exchange is the onset of hemolysis, occurring at degrees of exchange characteristic for ...

Two mono-cis-unsaturated phosphatidylcholine (PC) lipid molecules, having very different gel-liquid crystalline phase transition temperatures as a consequence of the relative positions of the double bond, exhibit PC:cholesterol phase diagrams that are very similar to each other and to that obtained previously for a fully saturated PC:cholesterol ...

Lipids and lipid-mixtures in boundary layers: from hydration lubrication to osteoarthritis [PDF]
The hydration layer surrounding the phosphocholine headgroups of single-component phosphatidylcholine (PC) lipids, or of lipid-mixtures, assembled at an interface greatly modifies the interfacial properties and interactions. As water molecules within the hydration layer are held tightly by the headgroup but are nonetheless very fluid upon shear, the ...
