The invention discloses walnut
meal protein peptide with dual activities of reducing
blood sugar and resisting depression and application of the walnut
meal protein peptide, and belongs to the technical field of
biology. The two kinds of walnut
meal protein peptides YALL and HPF are prepared, the two kinds of polypeptides both show the blood glucose reducing potential and the anti-depression activity, the glucose consumption of an HT22
high glucose depression
cell model can be increased by inhibiting the activity of alpha-
glucosidase, and the blood glucose reducing effect is achieved; by inhibiting the activity of MAO-A, the
corticosterone content of an HT22 high-glucose depression
cell model can be reduced, the levels of proinflammatory factors IL-6 and TNF-alpha can be effectively reduced, and the anti-depression effect is achieved. The walnut meal protein
peptide is derived from walnut
processing byproducts, is safe and free of toxic and side effects of chemical drugs, can be used for functional foods or
adjuvant therapy drugs, and meets the clinical requirements of
diabetes mellitus complicated with depression groups.
