[Physicochemical characteristics of calcium binding with plasma membranes of rabbit skeletal muscles].
It is established that Ca2+ binding with rabbit skeletal muscles plasmatic membrane depends on this cation concentration in the incubating medium. pH, temperature, incubation period and presence of Mg ions in the medium affect the Ca2+-binding ability of sarcolemma. The entropic changes observed in sarcolemma Ca2+ binding are due to conformation reconstructions of the membrane components.
