I have data on whole skeletal muscle tissue concentration of phosphatidylcholine (PC) and phosphatidylethanolamine (PE).
I do not have data on subcellular concentrations of PC and PE.
Still, I like to know how many percentage of the total concentration of PC or PE in the cell is accounted for by i.e. mitochondria, ER, plasma membrane etc.
Do anyone know a study addressing this question? My guess is that a study like this was performed in the 1970-90s.
I am looking for something like this:
Mitochondria: 50% of all PC and PE in the cell i located in the mitochondria.
ER: 30% of all PC and PE in the cell i located in the ER
Plasma membrane: 20% of all PC and PE in the cell i located in the plasma membrane.
Thank you!
Attached is a table showing the percentages of the various membranes in two types of cell: the hepatocyte and the exocrine cell. Note that the plasma membrane accounts for only 2-5% of the total cell membrane. The major portion of the total membrane is comprised of those of the E.R and the mitochondria (70 - 80% combined total).
Thank you very much!
Do you know if something similar exist for skeletal muscle? And is there a reference?
