GHK-Cu

GHK-Cu, or glycyl-L-histidyl-L-lysine:copper(II), is a small, naturally occurring tripeptide that readily forms a complex with copper ions. Its molecular structure consists of a glycine residue, a histidine residue, and a lysine residue, chelated with a copper(II) ion. This copper-binding capability is central to its biochemical characteristics and is a primary focus of scientific investigation. Research into GHK-Cu began in the early 1970s, with initial studies identifying its presence in human plasma. Subsequent investigations have explored its role in various biological processes at the cellular and molecular level. The peptide's interaction with copper is of particular interest, as copper is an essential trace element involved in numerous enzymatic reactions and protein functions. In research settings, GHK-Cu has been studied for its potential to modulate gene expression, influence cellular signaling pathways, and interact with extracellular matrix components. These properties are typically examined in cell culture models or through biochemical assays to elucidate the underlying mechanisms of action. The stability and bioavailability of the copper-peptide complex are also areas of continued scientific inquiry. Pure Peptides supplies GHK-Cu for laboratory and academic research purposes, facilitating studies into its fundamental biochemical roles and potential applications in material science or biotechnology.
