Concentrations of glutamic acid and proline were higher, but those of aspartic acid, alanine, lysine, and arginine were lower, (a) in the protein of subaleurone endosperm than in the protein of inner endosperm derived from HRW wheat and from a predominantly hard, mixed grist; and (b) in an interstitial protein concentrate than in an adherent protein concentrate from the mixed grist. Starch-gel electrophoresis showed a higher gliadin-albumin ratio in subaleurone than in inner endosperm, and in the interstitial than in the adherent protein concentrate. It is concluded that storage protein represents a larger proportion of the total protein in subaleurone endosperm than in inner endosperm, and in interstitial than in adherent protein.
