In a solution of the products of the hydrolysis of protein it is theoretically possible to bring about the reverse reaction, i.e. synthesis, in two ways: by concentrating the solution, and by raising the temperature. The theoretical considerations from which the first of these conclusions was deduced have been discussed in a previous paper (1). It is sufficient to recapitulate here, that the first method is predictable from an appropriate statement of the mass law. The experimental confirmation of the prediction was described by the authors (1). The second method is predictable from certain thermodynamical considerations of reversible reactions pointed out by Moore (2). He deduced the equilibrium equation Pα, = K Pnb, where Pα, and Pb, are respectively the osmotic pressures of the substrate and its product, and K is a constant. K is a symbol for the expression P0eC/RT, where P and e are constants, R is the gas constant, C is the chemical energy involved in the breakdown of 1 gram molecule of A into n gram molecules of B, and T is the absolute temperature.
