GHK is a tripeptide that coordinates copper(II) through nitrogen donor sites, creating a metal-peptide complex with properties different from unbound peptide or free copper. Binding studies examine stoichiometry, affinity, competing ligands, pH dependence, and exchange kinetics.

What researchers study
GHK-Cu is a copper-binding peptide complex studied in laboratory models involving extracellular matrix signaling and analytical metal-peptide interactions.
Tissue-model research uses controlled cell cultures, matrices, and biochemical assays to examine signaling associated with extracellular structure, migration, and laboratory injury models.
Laboratory tissue models simplify complex biology. They are useful for mechanism and method research but do not demonstrate healing, treatment, or clinical performance.
In controlled cell and matrix models, researchers study signaling associated with extracellular-matrix turnover, metalloproteinases, redox balance, migration, and gene expression. These models investigate mechanisms and cannot establish cosmetic, wound-healing, or therapeutic outcomes.
UV-visible spectroscopy, mass spectrometry, chromatography, and elemental methods can be combined to characterize both peptide and copper content. Copper can alter ionization and detector response, so matrix-matched controls and batch-specific methods are important.
