Chemical Identity and Structure
GHK-Cu is a naturally occurring copper-binding peptide complex composed of the tripeptide Glycyl-L-Histidyl-L-Lysine chelated with a copper (II) ion. This small molecular complex (molecular weight 401.9 g/mol) was initially identified in human plasma and exhibits a strong affinity for copper ions, forming a stable complex that enhances its biological activity and stability.

Biological Significance and Distribution
The peptide demonstrates age-dependent concentration levels in human plasma, with highest levels observed during youth and progressive decline with aging. This correlation with aging processes has generated significant scientific interest in its potential regenerative and protective properties. GHK-Cu functions as a signal peptide that influences multiple cellular pathways.

Primary Biological Activities and Mechanisms
• Tissue Repair and Regeneration: Promotes migration of various cell types to wound sites and accelerates wound healing processes through modulation of extracellular matrix components
• Antioxidant Protection: Provides defense against oxidative stress by neutralizing free radicals and supporting cellular antioxidant systems
• Anti-inflammatory Action: Reduces expression of inflammatory biomarkers and modulates inflammatory pathways
• Gene Expression Modulation: Influences activity of multiple genes involved in tissue remodeling, antioxidant defense, and inflammatory response
• Collagen Synthesis: Stimulates production of key structural proteins including collagen types I, II, and IV while reducing collagen degradation
