General description

Phosphatidylcholine belongs to the class of glycerophoshpolipids and contains choline as the head-group.[1] Choline is attached to the glycerol of fatty acids ester-bound to backbone.[1][2] It is the major phospholipid found in eukaryotic organism.[2]

Application

L-α-Phosphatidylcholine has been used:
  • to form a thin lipid film used in Kupffer cell depletion by liposome-encapsulated clodronate[3]
  • as a component of assay buffer used in γ-secretase in vitro assay[4]
  • in the preparation of substrate mix for its use in HPLC (high performance liquid chromatography) assay of 5-lipoxygenase enzyme activity[5]

Biochem/physiol Actions

A major structural phospholipid in brain, comprising approx. 15% of total lipid; primarily localized to gray matter.
It also acts as a source of lipid messengers/ bioactive lipids including: lysophosphatidylcholine, diacylglycerol, phosphatidic acid, lysophosphatidylcholine, arachidonic acid and platelet activating factor.[6] Phosphatidylcholine is produced in the liver by the CDP-choline (cytidine diphosphocholine) pathway.[7]

    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
