What is GHK-Cu?
GHK-Cu or Copper Tripeptide-1 is a peptide that naturally binds copper ions and consists of three amino acids—glycine, histidine, and lysine. GHK-Cu is a product of a copper ion interaction with a tripeptide molecule, which results in the formation of a bioactive compound that is extensively researched in biochemical and molecular science.
It was discovered while studying the elements of human plasma and later became of particular interest to researchers in the field of metal-peptide interaction and signaling pathways.
As far as research goes, the GHK-Cu peptide provides an interesting example of the ways in which peptide chains and metal ions may interact on a molecular level. The copper-binding ability of this peptide makes it very useful for scientific research into:
- Copper dependent signalling pathways
- Protein-protein interaction
- Cellular signalling pathways
- Extracellular matrix biology
- Molecular ageing studies
- Peptide biochemical studies
The peptide GHK-Cu is synthesised by means of modern synthetic peptide manufacture processes that mimic the native peptide chain. Synthesis provides researchers with a well-characterised laboratory grade compound, which can be used for analysis.
Current research into peptides still includes the study of GHK-Cu due to its unique structure, copper-binding ability and interaction with many different biological pathways. Research into this particular peptide chain involves investigation of molecular pathways, as opposed to developing any medical application.
GHK-Cu provided by research peptide providers is considered to be laboratory research reagents and is not approved in Australia for any therapeutic and human use.
Molecular Characteristics of GHK-Cu
GHK-Cu belongs to the category of synthetic peptide compounds and metal-binding peptide complexes. Its simple three-amino-acid structure allows researchers to investigate fundamental peptide interactions and copper-associated biochemical processes.
Basic Molecular Information
Peptide Structure

Purity Testing & Certificate of Analysis (COA)
Quality assessment is an integral component of peptide laboratory research. Prior to using any peptide in laboratory analyses, the knowledge about peptide identity and purity is a crucial aspect of laboratory work. In the case of GHK-Cu research peptides, analysis of the peptide often involves several procedures aimed at verifying the features of the production batch.
High-Performance Liquid Chromatography (HPLC)
High Performance Liquid Chromatography (HPLC) is one of the most popular analytical techniques in order to measure peptide purity. When performing an HPLC analysis, the peptides are separated into different parts. Therefore, researchers get the possibility to determine the percentage of the desired component in the sample.
During HPLC analysis, the following information could be obtained:
- Purity percentage
- Related compounds presence
- Impurity profile
- Consistency of batch
Higher purity percentage means that the sample has larger amount of desired peptides in comparison with other components. Those researchers who want to learn more about laboratory peptide analysis can use Understanding Peptide Purity and HPLC vs LC-MS Testing.
LC-MS Identity Verification
The Liquid Chromatography–Mass Spectrometry (LC-MS) technique is usually performed in addition to HPLC in order to prove the identity of peptides. While HPLC analyzes separation and purity, LC-MS gives information about molecular mass. By analyzing LC-MS, it is possible to verify the following aspects:
- Expected molecular weight
- Identity of the compound
- Molecular consistency
By using complementary analytical techniques, researchers have the opportunity to have more information about laboratory peptides.
Certificate of Analysis Explained
Certificate of Analysis (COA) refers to a batch-specific document providing information regarding the analysis of the research peptide. Information provided on a typical COA includes:
- Name of the product
- Identification number of the batch
- Date of testing
- Result of purity testing
- Method of analysis used
