 carbon connected directly to the amino nitrogen.

A triple Junction of the 

 gamma- gam tna- gamma tj^pe. 



If the connection is formed through the side 

 chains attached to the alpha carbon atoms, then it 

 appears that only a limited number of intermedi- 

 ate atoms can be involved, because at any point 

 beyond the third or gamraa carbon atom the 

 movements of the side chains would be too much 

 at random to form the connecting complexes 

 spontaneously. 



The branched hydrocarbon side chains con- 

 nected to the alpha carbon atoms of valine, leu-
