Title: **Yoh-ichi Koyama: Innovator in Collagen Peptide Composition and Hybrid Gels**

Introduction

Yoh-ichi Koyama is a prominent inventor based in Tokyo, Japan, known for his groundbreaking contributions to the fields of collagen peptide compositions and hybrid gel technology. With three patents to his name, Koyama's innovative approaches have the potential to revolutionize medical and cosmetic applications.

Latest Patents

Koyama's latest patents include the development of a novel collagen peptide composition production method, a DPP-4 inhibitor, and an antihyperglycemic agent. These inventions provide methods for producing collagen peptide compositions that exhibit high DPP-4 inhibitory activity and demonstrate excellent antihyperglycemic effects. The process involves using ginger rhizome-derived enzymes to break down collagen and/or gelatin solutions, generating peptides characterized by the sequence X-Hyp-Gly, where X represents an amino acid residue other than Gly, Hyp, and Pro.

Additionally, Koyama's patent for a Type I-Type IV collagen hybrid gel aims to maintain the characteristics of Type IV collagen while enhancing gel strength. This innovative gel is created by mixing 100 to 500 parts by mass of Type I collagen, which possesses fibrosis ability, with 100 parts by mass of Type IV collagen, known for its gelling ability. The resulting three-dimensional structure resembles a basement membrane of living tissue, providing an optimal environment for cell culture.
