GHK-Cu

Chemical & Structural Information

• Compound type: Copper-binding tripeptide complex
• CAS Number: 89030-95-5 for the 1:1 copper complex
• Molecular Formula: C14H23CuN6O4+
• Molecular Weight: approximately 402.92 g/mol
• Peptide Sequence: GHK - Gly-His-Lys bound to Cu2+

What It Is

GHK-Cu is a small three-amino-acid peptide bound to copper. It is widely studied in skin, collagen,
tissue-remodelling and hair-follicle research.

Research Focus

• Collagen and skin - laboratory studies examine fibroblasts, collagen, elastin and other parts of the skin matrix.
• Copper biology - copper is needed by several enzymes involved in tissue and antioxidant processes.
• Wound and blood-vessel models - research includes cell movement and angiogenesis.
• Hair follicles - GHK-Cu and related copper peptides are also studied in hair-follicle biology.

How It Is Studied

GHK binds copper strongly and forms a copper-peptide complex. Researchers study whether this helps control
copper-related enzyme activity and tissue-remodelling signals.
