GHK-Cu is a small copper-binding tripeptide — glycyl-L-histidyl-L-lysine (GHK) complexed with a copper(II) ion — making it structurally distinct from the larger peptides in the catalog.
The tripeptide backbone
GHK is just three amino acids, but the histidine imidazole and terminal amine give it a natural affinity for copper. Background on sequences: understanding amino acid sequences.
Copper coordination
The defining feature is the copper(II) complex; the metal is coordinated by the peptide, and this Cu binding is central to the biology explored in GHK-Cu mechanism of action and copper-peptide research.
Preparation and verification
The peptide is made by solid-phase synthesis and then complexed with a copper salt; identity and purity are confirmed by HPLC and mass spectrometry.
