Biochem/physiol Actions

C'est un phospholipide structural important du cerveau, qui représente environ 15 % des lipides totaux et qui est principalement localisé dans la substance grise.
Phosphatidylcholine is the major membrane phospholipid in eukaryotic cells, forming the structural component of these membranes. It also serves as a reservoir for several lipid messengers and a source for several bioactive lipids such as, lysophosphatidylcholine, phosphatidic acid, diacylglycerol, lysophosphatidylcholine, platelet activating factor, and arachidonic acid.

Application

L-α-Phosphatidylcholine is suitable for use:
  • as a component of human erythroid massive amplification culture (HEMAdef) medium for clinical expansion of human erythroblasts
  • in the chloride efflux assay to examine the chloride permeability of lipid vesicles conferred by soluble CLIC1
  • in an assay to measure solubilized wax synthase activity
  • as a component of buffer A used for the resuspension of the cholate-solubilized catalytic unit of adenylate cyclase
  • as a cryoprotectant for freezing ruminant sperm
  • as a substrate for the estimation of phospholipase activity
  • to make liposomes to assess their efficiency of recruitment of ARF (ADP ribosylation factor) and AP-1 (adaptor protein)
  • in the preparation of the isolated catalytic unit of soluble adenylate cyclase
