- Sequence
- Gly-His-Lys
- Size
- 3 AA (+ copper)
- Natural plasma peptide
- Anti-inflammatory mechanism
- Antioxidant, TNF-alpha modulation
- Skin, wound healing, anti-aging research
- Copper coordination
- None
- Central to biological activity
- Collagen synthesis
- No direct evidence
- Yes (promotes fibroblast activity)
- GHK-Cu's activity is substantially copper-dependent, with the copper ion playing a direct role in its antioxidant and tissue-remodeling activities. KPV has no metal coordination chemistry and its activity does not depend on metal ions.
- Research selection guidance: For NF-kB intestinal inflammation studies, KPV is the appropriate tool. For fibroblast collagen synthesis, extracellular matrix remodeling, or skin wound biology where copper chemistry is relevant, GHK-Cu is more directly applicable.
