Figure 2: SE-HPLC profiles of extractable (A; B) (obtained without sonication) and unextractable proteins (C; D) (obtained by sonicating the residue after removal of the extractable protein fraction in SDS-phospate buffer) of durum wheat semolina and einkorn flour. Panel A and B show peaks 1 and 2 corresponding to large (LPP) and small (SPP) polymeric proteins, respectively; peaks 3 and 4 and 5 corresponding to large (LMP) monomeric proteins and small (SMP) monomeric proteins, respectively
