This paper constitutes the second in a research series undertaken to clarify the inter-active relationships among soybean meal protein, calcium and phytic acid. The extent of bound calcium by cold insoluble fraction protein which is low in phosphorus content was examined by differential equilibrium dialysis, differing concentrations of calcium and phosphorus. The results indicate clearly that many molecules of calcium and phosphorus may be bound by a single protein molecule and that extent of calcium increases as phosphorous compounds in dialysis system such as phytic acid increase. The maximum number of bound calcium was calculated after statical equation by Klotz.
