Tripeptide-29 (Collagen Peptide) 200mg Topical Overview
Tripeptide-29 (Collagen Peptide) 200mg Topical from Peptide Science is the synthetic 3-amino-acid tripeptide based on the Gly-Pro-Hyp repeating unit of human type I collagen, supplied as a topical research formulation for in-vitro collagen-pathway research.
Compound Class and Mechanism
Tripeptide-29 corresponds to the repeating Gly-Pro-Hyp tripeptide that forms the core structural unit of the type I collagen triple helix. The hydroxyproline residue is the post-translationally modified amino acid that gives collagen its characteristic helical stability via interchain hydrogen bonding. Preclinical research has used the tripeptide as a research substrate for cell-culture studies of collagen synthesis, collagenase activity assays, and collagen-pathway-targeted dermal research.
