This tripeptide-copper complex (Gly-His-Lys + Cu) demonstrates exceptional affinity for copper (Ka ~10) and functions through multiple mechanisms: Primary Mechanisms: Copper delivery to cells and activation of copper-dependent enzymes (lysyl oxidase, superoxide dismutase) Matrix metalloproteinase (MMP) expression regulation through transcriptional mechanisms Tissue inhibitor of metalloproteinase (TIMP) upregulation for balanced matrix remodeling Gene expression modulation affecting hundreds of genes related to tissue repair, antioxidant response, and cell growth TGF- signaling pathway interactions influencing collagen synthesis and cell differentiation Research Applications: Collagen synthesis stimulation (types I and III collagen) Extracellular matrix remodeling balance through MMP/TIMP regulation Antioxidant enzyme expression (SOD, catalase, glutathione peroxidase) Anti-inflammatory cytokine modulation (IL-1, IL-6, TNF- reduction) Wound healing acceleration through multiple coordinated mechanisms Age-related tissue decline investigations (GHK-Cu levels decrease with aging) GHK-Cus characteristic blue-green color serves as visual verification of intact copper complex formation
