GHK-Cu: A Copper-Binding Tripeptide for Skin and Tissue Research

Overview

GHK-Cu (Glycyl-L-Histidyl-L-Lysine-Copper) is a naturally occurring copper-binding tripeptide first identified in human plasma. It plays a crucial role in wound healing, tissue repair, and has been extensively studied for its effects on skin regeneration, collagen production, and antioxidant activity.

Molecular Formula: C₁₄H₂₄N₆O₄Cu
Molecular Weight: Approximately 403 Da (peptide portion)
Sequence: Glycyl-L-Histidyl-L-Lysine with copper (II) ion

Mechanism of Action

GHK-Cu exerts its effects through multiple molecular pathways:

1. Copper Delivery and Cellular Transport

• Binds copper ions with high affinity
• Facilitates copper uptake by cells
• Supports copper-dependent enzymatic activities

2. Collagen and Elastin Synthesis

• Stimulates collagen production (types I, III, and VII)
• Enhances elastin synthesis
• Promotes glycosaminoglycan production
• Increases TIMP (tissue inhibitor of metalloproteinases)

3. Antioxidant Activity

• Scavenges free radicals
• Protects against oxidative damage
• Upregulates antioxidant enzyme expression

4. Anti-inflammatory Effects

• Modulates inflammatory cytokine production
• May reduce MMP (matrix metalloproteinase) activity
• Supports tissue remodeling

5. Stem Cell Activation

• Promotes stem cell proliferation
• Enhances stem cell differentiation
• Supports tissue regeneration
