Biosynthesis of phosphatidylcholine in bacteria
Progress in Lipid Research, 2003Phosphatidylcholine (PC) is the major membrane-forming phospholipid in eukaryotes and can be synthesized by either of two pathways, the methylation pathway or the CDP-choline pathway. Many prokaryotes lack PC, but it can be found in significant amounts in membranes of rather diverse bacteria and based on genomic data, we estimate that more than 10% of ...

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.

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 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

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 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.
