Ilydrolyzinjs; pectin com- 

 pounds to monosaccharids. 

 Hydrolyzing starch to d-glu- 

 cose (probably several steps, 

 involving perhaps several 

 enzymes). 



Sphtting d-glucose into ethyl 

 alcohol and CO2. 

 Hydrolyzing amygdalin to 

 HCN, d-glucose and oil of 

 bitter almonds. 

 Acting on fats, saponifying 

 and emulsifjang them. 

 Hydrolyzing protein com- 

 pounds to different degrees of 

 simplicity. 



IMany kinds, bringing about 

 numerous oxidations within 

 the plant. 



Decomposing peroxides in the 

 plant. 



Bringing about reducing proc- 

 esses in the plant. 

 Under this head are grouped a 

 number of totall}^ unrelated 

 substances that do not come 

 under anj^ of the foregoing 

 heads and that are not numer- 

 ous enough to form classes by 

 themselves. 



Produced by bacterial fermen- 

 tations of celluloses. 

 In the oil from the seeds of 

 some pines. 



In Mercitrialis pcrcnuis and 

 M. annua. 



In Chenopodium, in blossoms 

 of Crataegus, and of pear, etc. 

 Apparently one of the first 

 steps in the photosynthesis of 

 CO2 and HO2 to form carbo-
