Autoxidation of phosphatidylcholine liposomes
Lipids, 1982AbstractAutoxidation 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.

Bovine liver phosphatidylcholine transfer protein (PC-TP) has been expressed in Escherichia coli and purified to homogeneity from the cytosol fraction at a yield of 0.45 mg PC-TP per 10 mg total cytosolic protein. In addition, active PC-TP was obtained from inclusion bodies.

The solubility of the three steroid hormones, progesterone, testosterone, and estradiol-17 beta in water and phosphatidylcholine vesicles was measured after shaking and ultrasonication. All three steroids have low water solubility, which increases considerably at sonication for testosterone and estradiol-17 beta. The phosphatidylcholine vesicles have a

Dipalmitoyl phosphatidylcholine (DPPC) and egg phosphatidylcholine (egg PC) are not completely miscible at all temperatures. Their phase diagram was determined by differential scanning calorimetry (DSC) of aqueous mixtures of the two. From the integrated DSC curves we obtained the enthalpy of solution of DPPC in egg PC, Δhs, as a function of the mole ...

The structures of bile phosphatidylcholines
Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1973Abstract Phosphatidylcholines from the bile of pigs, sheep and cows were isolated and the fatty acid composition of each determined. Linoleic acid was the principal poly-unsaturated fatty acid of pig bile phosphatidylcholine but that from the ruminants contained appreciable amounts of 9-cis, 11-trans-octadecadienoic acid, 9-cis, 11 -trans, 15-cis ...

Synthesis of a photocleavable bola-phosphatidylcholine
Bioorganic & Medicinal Chemistry, 2023Phosphatidylinositol transfer proteins (PITPs) are ubiquitous in eukaryotes and are involved in the regulation of phospholipid metabolism, membrane trafficking, and signal transduction. Sec14 is a yeast PITP that has been shown to transfer phosphatidylinositol (PI) or phosphatidylcholine (PC) from the endoplasmic reticulum to the Golgi.

The interaction of ions with phosphatidylcholine bilayers
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1977Abstract The interaction of lanthanides and other cations with phosphatidylcholine bilayers present as single bilayer vesicles in 2H2O has been investigated in terms of stoichiometry, apparent binding constants and environmental conditions. Lanthanides are shown to form 2 : 1 (molar ratio) phosphatidylcholine to metal ion complexes.

The effect of dicarboxylic phosphatidylcholines (glutaryl phosphatidylcholine) on the stability and phase transition of phosphatidylcholine liposomes is examined by using liposomes prepared with egg phosphatidylcholine or dipalmitoyl phosphatidylcholine and by varying the surface charge by addition of dicetyl phosphate.

Freeze-fracture electron microscopy is used to study the rippled texture in pure dimyristoyl and dipalmitoyl phosphatidylcholine membranes and in mixtures of dimyristoyl phosphatidylcholine and cholesterol. Evidence is presented that the apparent phase transition properties of multilamellar liposomes may be dependent on the manner in which liposomes ...

Phase diagram has been determined with X-rays for bilayer membranes of mixed lipids of dioleoyl-phosphatidylcholine/dipalmitoyl-phosphatidylcholine in water. Observed liquidus lines were reproduced well by calculation on the assumption of ideal mixing of the two lipids.
