GHK-Cu is a copper-associated tripeptide research material based on the amino-acid sequence Gly-His-Lys. The peptide coordinates with copper to form a metal-peptide complex suitable for controlled laboratory and analytical studies.

Unlike a simple uncomplexed peptide, GHK-Cu can be represented in different coordination states and stoichiometries. PubChem currently includes a GHK-Cu record with formula C₂₈H₄₈CuN₁₂O₈ and molecular weight 744.3 g/mol, as well as 1:1 copper-tripeptide representations around 400.9–402.9 g/mol.

For accurate website specifications, the precise copper-to-peptide ratio, salt form, molecular formula, molecular weight, and analytical identity should therefore be taken from the applicable Certificate of Analysis.

Research Applications

GHK-Cu may be examined in controlled non-clinical research involving:

  • Copper-peptide coordination studies
  • Peptide characterization
  • Metal-binding research
  • Molecular interaction analysis
  • Structure-function studies
  • Analytical peptide comparison
  • Stability assessment
  • Non-clinical biochemical and cellular models

Any experimental observations should remain specific to the applicable research system and should not be interpreted as evidence of therapeutic, cosmetic, regenerative, or clinical effectiveness.

Structural Information

The peptide portion of GHK-Cu consists of:

Gly-His-Lys

One-letter representation:

GHK

Copper coordination forms the GHK-Cu complex. Because the metal-to-peptide stoichiometry can alter the reported molecular formula and molecular weight, a universal single molecular value should not be used when the exact supplied form is unknown.

Analytical Identification

Relevant analytical characterization may include:

  • Peptide identity confirmation
  • Copper-complex verification
  • Molecular mass assessment
  • Copper-content analysis
  • Chromatographic purity testing
  • Structural characterization
  • Lot-specific quality testing

Specifications & Documentation

Lot-specific documentation should be reviewed for:

  • Material identity
  • Peptide sequence
  • Copper coordination form
  • Copper-to-peptide ratio
  • Molecular formula
  • Molecular weight
  • Salt or counter-ion form
  • Purity specification
  • Analytical testing
  • Lot or batch information
  • Certificate of Analysis
  • Storage requirements

Authenticated product-specific documentation should take precedence over generalized database values.

Storage & Handling

Store according to the conditions specified on the product label and Certificate of Analysis. Protect the material from environmental conditions that could compromise peptide or metal-complex integrity.

Handling should follow established laboratory procedures appropriate for research materials.
