Peptides from potato protein and Palmaria palmata showed antidiabetic activity mediated byregulating blood glucose and insulin changes in streptozotocin (STZ)-induceddiabetic mice.235,236 Aglycin with 37 amino acidsoriginated from soy could improve glucose tolerance and insulin resistancevia increasing the IR/IRS1 insulin receptor signaling pathway andGLUT4 translocation in the skeletal muscle of T2D mice.92 It was found that these peptides at 50 mg/kgof BW could help to alleviate diabetes. The gene discussed is IRS1; the disease is diabetes mellitus.
