Physiology, question cytosol

There is a similar situation in all the membranes in contact with the cytosol PC is a major constituent in the outer membrane from plastids and mitochondria and in the peroxisomal membrane (table l). One can question whether this situation has any physiological significance or results from the functionning of the phospholipid transfer proteins that are present in the cytosol. There is almost no redistribution of this PC whithin the chloroplast since phospholipase C treatment destroy almost all the envelope PC without rupture or modification of the outer envelope membrane structure. ...
