1. Introduction
Copper Peptide, commonly referred to as GHK-Cu, is one of the most extensively studied bioactive copper complexes in modern cosmetic science, regenerative medicine, and pharmaceutical biotechnology. Chemically, GHK-Cu is the copper(II) complex of the naturally occurring tripeptide glycyl-L-histidyl-L-lysine (GHK). The compound has attracted substantial industrial and scientific attention because of its remarkable biological activities, including wound healing promotion, collagen synthesis stimulation, anti-inflammatory effects, antioxidant activity, skin remodeling, and hair growth enhancement.
The molecular formula of GHK-Cu is generally represented as C14H24CuN6O4, with a molecular weight of approximately 340.9 g/mol. The CAS registry number for the copper complex is 49557-75-7. In its pure form, GHK-Cu typically appears as a blue to violet crystalline powder due to the coordination interaction between Cu2+ ions and peptide ligands.
Over the past three decades, GHK-Cu has transitioned from a laboratory research molecule into a commercially valuable ingredient used in high-end skincare formulations, wound care products, tissue engineering systems, and biomedical research. Its increasing demand has stimulated continuous improvements in peptide synthesis technologies, copper chelation methods, purification systems, and quality control standards.
This article provides a comprehensive overview of the chemical properties, manufacturing processes, analytical characterization, formulation considerations, biological mechanisms, industrial applications, and future development trends of Copper Peptide from the perspective of a professional chemical engineer.
2. Chemical Structure and Molecular Characteristics
2.1 Molecular Structure
GHK-Cu is formed by the coordination of one copper(II) ion with the tripeptide glycyl-L-histidyl-L-lysine.
The peptide sequence is:
Glycine – Histidine – Lysine
The histidine residue plays a critical role in copper binding because the imidazole nitrogen atom provides strong coordination capability toward Cu2+ ions.
The copper ion is usually coordinated through:
- The terminal amino group
- The amide nitrogen
- The histidine imidazole nitrogen
- Carboxyl oxygen atoms
This coordination creates a highly stable chelate complex.
The molecular structure can be represented schematically as:
GHK + Cu2+ → GHK-Cu
The blue coloration of the compound is attributed to d-d electron transitions within the Cu2+ coordination environment.
2.2 Physicochemical Properties
Appearance
- Blue powder or blue crystalline solid
Solubility
- Highly soluble in water
- Slightly soluble in ethanol
- Insoluble in nonpolar solvents
pH Stability
GHK-Cu exhibits optimal stability under weakly acidic to neutral conditions:

Under strongly alkaline conditions, copper hydroxide precipitation may occur, leading to instability and degradation.
Thermal Stability
- Stable under refrigerated conditions
- Sensitive to prolonged exposure to high temperature
- Peptide hydrolysis increases above 60°C
Oxidation Sensitivity
Although copper itself participates in redox reactions, the peptide ligand stabilizes Cu2+ and minimizes uncontrolled oxidation. However, excessive exposure to oxidizing environments may still induce peptide degradation.
