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

Biochem/physiol Actions

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.
A major structural phospholipid in brain, comprising approx. 15% of total lipid; primarily localized to gray matter.

The stoichiometry of c subunits in the H(+)-transporting F(o) rotary motor of ATP synthase is uncertain, the most recent suggestions varying from 10 to 14. The stoichiometry will determine the number of H(+) transported per ATP synthesized and will directly

In this study, the heteromeric N-methyl-D-aspartate (NMDA) receptor channels composed of NR1a and NR2A subunits were expressed, purified, reconstituted into liposomes, and characterized by using the patch clamp technique. The protein exhibited the expected electrophysiological profile of activation by glutamate
