46 THE VEGETABLE PROTEINS 



In respect to its behaviour toward heat leucosin resembles the animal 

 proteins more closely than do the globulins, which constitute the greater 

 part of the reserve protein of most seeds. We have already stated the 

 reasons for believing leucosin to be chiefly contained in the embryo of 

 the seed, and it is probable that the physiologically active seed proteins, 

 in this respect as well as in others, more closely resemble the physio- 

 logically active animal proteins than do the true reserve proteins of 

 the seed.
