8 The antagonistic action between KgSO^. 

 and MgCl2 for wheat-amylase 



9 The antagonistic action between CaClg 

 and MgSOj^ for wheat-amylase 

 Table 10. 



The results show the antagonistic effects between different cathions and anions 



for wheat-amylase. At last I exermined Loeb's socalled apparent antagonistic 



effects between the decomposition products of protein and potassium chloride for 



wheat-amylase and got the following results. 



10 The antagonistic action between glycocoll 

 and KCl for wheat-amylase 



Table 1 1 . 



In this case we can also observe the antagonistic effect between gl\-cocull and 

 KCl for wheat-amylase. 



CONCLUSTON 



From the results we know the antagonistic effects between different salts — of 

 different cathions and same anions as KCl and CaCl2, NaCl and CaCl^, NaCl and 

 KCl or CaCl^ and MgCl.^, and of different anions and same cathions as KCl and 

 KojSO,^, KNO3 and K^SO.^ and of different cathions and different anions as 

 K^SO^ and MgClj or CaCl^ and MgSOj. — for amylase of wheat-seedling and 

 for Takadiastase. Farther more the apparent antagonistic eff.jct is observed 

 between glycocoll and KCl for the same enzym.
