[Phosphatidylcholine transfer between liposomes and mitochondria. Testing system for the study of specific phospholipid exchange].
A system consisting of liposomes and mitochondria for studying the exchange of specific phospholipids is described. The liposomes were prepared from phosphatidylcholine labelled with 14C-palmitic acid. The transfer of liposomes to the mitochondria is specifically stimulated 2- to 3fold by the pH 5.1 supernatant, and proceeds in a linear fashion for 90 min.
