yzate. Hydrolyzates prepared by the action of alkali and of 

 dilute acid were also investigated, but only a few different 

 peptides were obtained. From the combined results it was 

 possible to determine the five sequences listed in Table III as 

 being present in fraction B. The structure of the peptides from 

 which the sequence was deduced is indicated by underlining.
