Barbiturate Interaction with Phosphatidylcholine [PDF]

open access: greenProceedings of the National Academy of Sciences, 1972
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 ...

An efficient synthesis of phosphatidylcholines.

open access: yesJournal of Lipid Research, 1990
This article deals with two of the major steps involved in phospholipid synthesis: the preparation of the optically pure precursors, sn-glycero-3-phosphocholine (GPC) and -ethanolamine, from a convenient lipid source such as egg yolk, and acylation of ...

Mass spectrometry of the phosphatidylcholines: dipalmitoyl, dioleoyl, and stearoyl-oleoyl glycerylphosphorylcholines

open access: hybridJournal of Lipid Research, 1971
Mass spectra of the diacyl glycerylphosphorylcholines have been obtained using a direct insertion probe, with a source temperature of 250°C at an ionizing potential of 70 ev.

Molecular species of biliary phosphatidylcholines in gallstone patients: the influence of treatment with cholic acid and chenodeoxycholic acid

open access: hybridJournal of Lipid Research, 1981
Molecular species of phosphatidylcholines were analyzed in hepatic and gallbladder bile obtained from six subjects with adenomyoma of the gallbladder (gallstone-free controls) and 27 gallstone patients undergoing cholecystectomy.

Phosphatidylcholine synthesis in yeast.

open access: hybridJournal of Lipid Research, 1988
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.

The Expanded Endocannabinoid System Contributes to Metabolic and Body Mass Shifts in First-Episode Schizophrenia: A 5-Year Follow-Up Study

open access: yesBiomedicines, 2022
Alterations in the expanded endocannabinoid system (eECS) and cell membrane composition have been implicated in the pathophysiology of schizophrenia spectrum disorders. We enrolled 54 antipsychotic (AP)-naïve first-episode psychosis (FEP) patients and 58

Miscibility of Sphingomyelins and Phosphatidylcholines in Unsaturated Phosphatidylcholine Bilayers [PDF]

open access: yesBiophysical Journal, 2015
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 ...

Associations of Early Pregnancy Metabolite Profiles with Gestational Blood Pressure Development

open access: yesMetabolites, 2022
Blood pressure development plays a major role in both the etiology and prediction of gestational hypertensive disorders. Metabolomics might serve as a tool to identify underlying metabolic mechanisms in the etiology of hypertension in pregnancy and lead ...

Mucosal Protection by Phosphatidylcholine [PDF]

open access: yesDigestive Diseases, 2012
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

Unique Distribution of Diacyl-, Alkylacyl-, and Alkenylacyl-Phosphatidylcholine Species Visualized in Pork Chop Tissues by Matrix-Assisted Laser Desorption/Ionization–Mass Spectrometry Imaging

open access: yesFoods, 2020
Phosphatidylcholine (PC) is the major phospholipid in meat and influences meat qualities, such as healthiness. PC is classified into three groups based on the bond at the sn-1 position: Diacyl, alkylacyl, and alkenylacyl. To investigate their composition
