The action of sodium soaps on trypsin. J. B. 

 Brown. The sodiinn soaps of the higher fatty 

 acids have been found to destroy trypsin very 

 rapidly. The amount of destruction of enzyme 

 depends on the concentration of the soap and the 

 time of exposure of enzyme to soap. The pres- 

 ence of protein substrate protects the enzyme 

 and lessens the destruction. The satured and 

 unsatured soaps are about equally destructive. 

 Sodium soaps destroy the autolytic enzymes of 

 dog liver and the ptyalin of human sahva. The 

 action of soaps on these enzymes is much greater 

 than can be accounted for as a Pjj effect.
