Journal of the Indian Chemical Society September 1935

1935

The object of the present investigation was to show whether the salts protect the amylase against destruction and whether there is a parallelism between the influence of these salts on the stability and on the activity of the enzyme. [...] Thus the salts protect the amylase from destruction at more acid region of the optimum pa. At the optimum and at the alkaline side of the optimum pa they have no influence on the stability of the enzyme; on the contrary they hasten the destruction of the enzyme at high salt concentrations. [...] Secondly the order of action of the anions and cations of the salts investigated is similar both for the protection of the enzyme and for the accelertion of the activity of the enzyme. [...] If it be granted as exceedingly probable that the glycerides exist in the pure stable form in solution it would be of interest to measure the heats of the solution of the two forms of each triglyceride in various organic solvents and from the results thus obtained calculate the heat of transition of one form into the other. [...] If the specific heats of the two forms are not very different the difference in the latent heats of fusion of the two forms should give the heat of transition of one form into the other.
