Overview
GHK-CU is listed under Cellular Research.
GHK-Cu (glycyl-L-histidyl-L-lysine copper complex) is a naturally occurring copper-binding tripeptide first isolated from plasma samples in 1973. The peptide consists of three amino acids (Gly-His-Lys) complexed with copper(II) ions through high-affinity chelation. This coordination stabilizes copper in a redox-controlled form suitable for experimental systems. Endogenous GHK-Cu concentrations have been shown to vary across biological samples, making it a compound of significant interest in gene expression and metalloprotein research.
