ghk-cu copper coordination sites a) Domain schematic for the production of GHK-tagged protein. (b) Site-Specific Detection of Copper–Peptide Coordination

Site Specific Detection of CopperPeptide Coordination in Solution Phase by Two Dimensional Infrared Spectroscopy The Journal of Physical Chemistry Letters GHK Cu 50mg Purity Peptides A peptide can change character when it holds a metal ion. GHK Cu is a coordination complex: the Gly His Lys tripeptide provides nitrogen rich binding sites, especially around the N terminus and histidine imidazole. In laboratory GHK Cu (glycyl L histidyl L lysine copper complex) is a naturally occurring tripeptide bound to a copper ion. It is formed by the coordination of the peptide GHK with copper (Cu) and has been identified in Figure 3 from GHK Copper Peptide in Skin Remodeling and Anti Aging !
