GHK-Cu (Copper Tripeptide-1)

GHK-Cu, also known as Copper Tripeptide-1 or Prezatide Copper, is a naturally occurring peptide–metal complex composed of the amino acids glycine, histidine, and lysine coordinated with a divalent copper ion (Cu²⁺).

This complex consists of the tripeptide GHK (Gly-His-Lys) chelated to copper, forming a stable coordination structure studied in cellular signaling and peptide–metal interaction research models.

Structural Composition

GHK-Cu is formed by chelation of a copper ion (Cu²⁺) to the tripeptide GHK. The copper ion coordinates primarily with:

• The nitrogen atom within the imidazole ring of histidine
• The terminal amino group of the peptide backbone

This coordination complex is studied in laboratory settings for its stability, metal-binding characteristics, and peptide-mediated signaling mechanisms.

Research Context

In controlled research environments, GHK-Cu has been examined in studies involving:

• Peptide–metal interaction analysis
• Cell signaling pathway models
• Extracellular matrix research
• Gene expression pathway investigations
• Redox and copper transport research

As a naturally occurring peptide complex, GHK-Cu is frequently referenced in biochemical and molecular signaling literature. All descriptions are limited strictly to laboratory and investigational research contexts.

No therapeutic or medical claims are made.
