GHK-Cu: The Copper-Binding Tripeptide in Published Research
GHK-Cu has been studied for over 50 years. A look at the published literature on copper transport and tissue remodeling research.
GHK-Cu (Glycyl-L-histidyl-L-lysine copper complex) was first isolated from human plasma albumin in 1973 by Loren Pickart. Over 50 years of published research have examined this tripeptide's biochemical properties.
Structure and Copper Binding
GHK has a high affinity for Cu2+ ions. The copper binding involves the alpha-amino group, imidazole nitrogen of histidine, and the deprotonated amide nitrogen. The resulting complex, GHK-Cu, has different properties than GHK alone.
Published Research Areas
Collagen Regulation: Early studies by Pickart characterized GHK's effects on collagen synthesis and degradation in cell culture models.
Antioxidant Enzymes: Research has examined GHK-Cu effects on superoxide dismutase and other antioxidant enzyme expression.
Gene Expression Profiling: A 2012 study published in Advances in Clinical Chemistry examined the effects of GHK-Cu on gene expression in cultured cells, identifying over 4000 regulated genes.
Wound Models: Animal studies have used GHK-Cu in wound healing models, measuring inflammatory markers and tissue remodeling endpoints.
Research Considerations
Concentration matters significantly in GHK-Cu research. Published data shows biphasic dose-response relationships in some assays. Researchers should review published protocol parameters carefully.
