Tripeptide-29

INCI: TRIPEPTIDE-29

CAS Number
2239-67-0
Function
Collagen-mimetic biomimetic peptide that replicates the Gly-Pro-Hyp (glycine-proline-hydroxyproline) tripeptide sequence — the fundamental repeating unit of the collagen triple helix. Provides direct structural reinforcement and stimulates collagen synthesis by presenting a native ECM sequence to fibroblasts. Mechanism differs from signal peptides: Tripeptide-29 mimics the structural building block rather than a matrikine fragment.
