The Molecular Foundation of BPC157
Understanding BPC157 begins with its molecular structure and biochemical properties.
Chemical Structure and Stability
BPC157 consists of a specific sequence of 15 amino acids (Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val) derived from a protective protein in gastric juice. Research has identified several noteworthy characteristics:
