Fractionation of the protein complex in Hiproly (CI 3947) and Hiproly Normal (CI 4362) barleys showed that the salt-soluble protein fraction accounted for 41.8 and 43.5% of the total lysine, respectively. Salt- soluble and glutelin fractions together accounted for 78.7% of the total lysine in Hiproly and 80.6% in Hiproly Normal. Salt-soluble protein fractions from these two barleys contained identical protein components, as indicated by comparison of the electrophoretic mobilities of components of chromatographic fractions. One chromotographic fraction accounted for 50.3% of the lysine in the salt- soluble proteins of Hiproly and 43.5% in Hiproly Normal. The first three chromatographic fractions from the salt-soluble protein of Hiproly contained 52% more lysine than did comparable fractions in Hiproly Normal. These fractions contained higher percentages of aspartic acid, lysine, and valine and lower percentages of tyrosine, glutamic acid, and cystine/2 in Hiproly than in Hiproly Normal.
