Cy5-Labeled Phosphatidylcholine

Russian Journal of Bioorganic Chemistry, 2021
Fluorescent lipid probes are widely used as tools for studying the properties of biological membranes and for studies of such biological functions of lipids as metabolic pathways and the molecular nature of diseases. In this report, we propose the new Cy5-labeled phosphatidylcholine (Cy5-PC) fluorescent lipid probe and describe its geometrical ...

Phosphatidylcholine and cell death

Biochimica et Biophysica Acta (BBA) - Molecular and Cell Biology of Lipids, 2002
Phosphatidylcholine (PC) constitutes a major portion of cellular phospholipids and displays unique molecular species in different cell types and tissues. Inhibition of the CDP-choline pathway in most mammalian cells or overexpression of the hepatic phosphatidylethanolamine methylation pathway in hepatocytes leads to perturbation of PC homeostasis ...

The contribution of serum phosphatidylcholine and lysophosphatidylcholine to lymph phosphatidylcholine

Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1980
1. The contribution of serum phosphatidylcholine and 1-acyl lysophosphatidylcholine to chylomicron and mesenteric lymph lipoproteins of heavier buoyant density was studied in rats with catheters placed in the jugular vein, duodenum, common bile duct and mesenteric lymph duct.

Autoxidation of phosphatidylcholine liposomes

Lipids, 1982
AbstractAutoxidation of pure soybean phosphatidylcholine liposomes at 40 C was found to proceed without an observed induction period, but otherwise, the rates of disappearance of the linoleic acid (70% of total) and linolenic acid (6% of total) followed typical autocatalytic kinetics.

Temperature Dependence of Dipalmitoyi Phosphatidylcholine/Diheptanoyl Phosphatidylcholine Aqueous Mixtures

Proceedings, annual meeting, Electron Microscopy Society of America, 1991
There is great interest in the process of lipid self-assembly, especially the microstructure formed from lipid mixtures. Spontaneous unilamellar vesicles have been reported by Roberts from mixtures of long-chain lecithins and short-chain lecithins. Alone, dipalmitoyi phophatidylcholine (DPPC) forms normal multilamellar phases, a solid Lβ phase up to ...

The preference of cholesterol for phosphatidylcholine in mixed phosphatidylcholine-phosphatidylethanolamine bilayers

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1976
The following phosphatidylethanolamines were studied by differential scanning calorimetry: 1,2-dipalmitoleoyl-, 1,2-dioleoyl-, 1,2-dilauroyl-, 1,2-dielaidyl-, 1,2-dimyristoyl- and 1,2-dipalmitoyl-sn-glycero-3-phosphoryl-ethanolamine. The saturated and trans-unsaturated species underwent thermotropic phase transitions at temperatures about 20-30 degrees

Electrospray ionization/tandem quadrupole mass spectrometric studies on phosphatidylcholines: The fragmentation processes

Journal of the American Society for Mass Spectrometry, 2003
We applied low-energy collisionally activated dissociation (CAD) tandem quadrupole mass spectrometry to study the fragmentation pathways of the [M + H]+ and [M + Li]+ ions of phosphatidylcholine (PC), generated by electrospray ionization (ESI).
