General description

Phosphatidylcholine belongs to the class of glycerophoshpolipids and contains choline as the head-group. Choline is attached to the glycerol of fatty acids ester-bound to backbone. It is the major phospholipid found in eukaryotic organism.

Application

L-α-Phosphatidylcholine has been used:
  • to form a thin lipid film used in Kupffer cell depletion by liposome-encapsulated clodronate
  • as a component of assay buffer used in γ-secretase in vitro assay
  • in the preparation of substrate mix for its use in HPLC (high performance liquid chromatography) assay of 5-lipoxygenase enzyme activity

Biochem/physiol Actions

It also acts as a source of lipid messengers/ bioactive lipids including: lysophosphatidylcholine, diacylglycerol, phosphatidic acid, lysophosphatidylcholine, arachidonic acid and platelet activating factor. Phosphatidylcholine is produced in the liver by the CDP-choline (cytidine diphosphocholine) pathway.
A major structural phospholipid in brain, comprising approx. 15% of total lipid; primarily localized to gray matter.

Packaging

Packaged under Argon

Preparation Note

Prepared by a modification of the procedure of Singleton, W.S., et al., J. Am. Oil Chem. Soc., 42, 53 (1965).

Nosocomial infections with Enterococcus faecalis are an emerging health problem. However, drug efflux pumps contributing to intrinsic drug resistance are poorly studied in this Gram-positive pathogen. In this study, we functionally investigated seven heterodimeric ABC transporters of E. faecalis that

Invasive infections by fungal pathogens cause more deaths than malaria worldwide. We found the ergoline compound NGx04 in an antifungal screen, with selectivity over mammalian cells. High-resolution chemogenomics identified the lipid transfer protein Sec14p as the target of NGx04 and
