Brain function regulating agent, and food or beverage product containing same

Abstract

A brain function regulating agent contains a peptide comprising an amino acid sequence represented by Glu-Hyp-Gly, a salt thereof, or a chemically modified product thereof.

1 . A brain function regulating agent comprising a peptide comprising an amino acid sequence represented by Glu-Hyp-Gly, a salt thereof, or a chemically modified product thereof. 
     
     
         2 . The brain function regulating agent according to  claim 1 , wherein the peptide, salt thereof or chemically modified product thereof is a tripeptide represented by Glu-Hyp-Gly, a salt thereof, or a chemically modified product thereof. 
     
     
         3 . The brain function regulating agent according to  claim 1 , wherein the peptide is derived from collagen. 
     
     
         4 . The brain function regulating agent according to  claim 1 , wherein the peptide has a weight average molecular weight of 315 or more and 10,000 or less. 
     
     
         5 . The brain function regulating agent according to  claim 1 , wherein the brain function regulating agent is a brain function improving agent or a brain function decline preventing agent. 
     
     
         6 . The brain function regulating agent according to  claim 1 , wherein the brain function regulating agent has a cerebral nerve cell differentiation promoting action. 
     
     
         7 . The brain function regulating agent according to  claim 1 , wherein the brain function regulating agent has a cerebral nerve cell death suppressive action. 
     
     
         8 . The brain function regulating agent according to  claim 1 , wherein the brain function regulating agent has a memory or cognitive function improving action. 
     
     
         9 . A food or beverage product comprising the brain function regulating agent according to  claim 1 .
