A peptide selected from the group consisting of Ala-Hyp-Gly, Hyp-Gly-Pro, Leu-Hyp, Glu-Hyp, Gly-Pro-Hyp, Pro-Ala, Hyp-Gly and Pro-Hyp, or a pharmaceutically acceptable salt thereof has a myoblast differentiation promoting effect superior to conventional arts.

Myoblast differentiation promoter

A collagen peptide mixture containing three or more kinds selected from Glu-Hyp-Gly, Glu-Hyp, Leu-Hyp-Gly, Pro-Ala, Ser-Hyp, Ala-Hyp-Gly, chemically-modified substances thereof and pharmaceutically acceptable salts thereof, and at least one peptide selected from the group consisting of Glu-Hyp-Gly, Glu-Hyp, Leu-Hyp-Gly, Pro-Ala, Ser-Hyp, Ala-Hyp-Gly, Pro-Hyp-Gly, Leu-Hyp, Ile-Hyp, Ser-Hyp-Gly, Gly-Pro-Hyp, (Pro-Hyp-Gly), Pro-Hyp, Hyp-Gly, Pro-Gly, Pro-Pro and Ala-Hyp or a chemically-modified substance thereof or a pharmaceutically acceptable salt thereof have DPPTV inhibitory activity and/or GLP-1 secretion accelerating activity, and hence are effective as a therapeutic or preventive agent or the like for diabetes.

Therapeutic or preventive agent for diabetes

A problem that the present invention is to solve is to provide: a main body of a peptide molecule which is effective for inhibition of various maladies such as osteoporosis, osteoarthritis and pressure ulcer, particularly, a dipeptide which is easy to absorb into a body in an intestine; a collagen peptide which comprises the dipeptide as an essential dipeptide; and a malady inhibitor which comprises the dipeptide as an essential effective component. As a means of solving such a problem, a collagen peptide according to the present invention is characterized by comprising a dipeptide having a structure of Hyp-Gly as an essential dipeptide. A dipeptide according to the present invention is characterized by having a structure of Hyp-Gly. A malady inhibitor according to the present invention is characterized by comprising a dipeptide having a structure of Hyp-Gly as an essential effective component.
