Heating leaf protein of agricultural crops with 2 N H 2 SO 4 removed 5–10% of its dry weight as carbohydrate, of which less than half was reducing sugar; arabinose, galactose, xylose and sometimes a little glucose were found for all the crops studied. Pronase released soluble carbohydrate from red clover and wheat protein as large fragments which gave pentose, mainly arabinose, on heating with 0.2 N H 2 SO 4 , and galactose and glucose on heating with 2 N H 2 SO 4 . Similar results on graded acid hydrolysis were shown by a fraction from red clover liquor, the soluble material remaining after heat‐precipitation of the protein.
