Choline Permeability in Cardiac Muscle Cells of the Cat
Permeability of the cardiac cell membrane to choline ions was estimated by measuring radioactive choline influx and efflux in cat ventricular muscle. Maximum values for choline influx in 3.5 and 137 mM choline were respectively 0.56 and 9 pmoles/cm(2).sec. In 3.5 mM choline the intracellular choline concentration was raised more than five times above the extracellular concentration after 2 hr o...

متن کاملPermeability of Frog Skeletal Muscle Cells to Choline
Using choline-methyl-C(14) as a tracer, it has been shown that choline(+) penetrates into the cells of resting frog skeletal muscle at a rate similar to that of Na(+), and that it escapes from these cells much more slowly than does Na(+). Some implications of these findings are discussed.

Using choline-methyl-C 14 as a tracer, it has been shown that choline + penetrates into the ceils of resting frog skeletal muscle at a rate similar to that of Na +, and that it escapes from these cells much more slowly than does Na +. Some implications of these findings are discussed. Permeability of Frog Skeletal Muscle Cells to Choline It is generally believed that choline ions do not penetra...
