Overview
GHK‑Cu (Glycyl‑L‑Histidyl‑L‑Lysine‑Copper) is a naturally occurring tripeptide–copper complex found in human plasma and other biological fluids. It is widely utilized in in vitro and laboratory‑based research involving peptide–metal interactions, cellular signaling pathways, and models of tissue‑matrix regulation. GHK‑Cu is of particular interest for studies examining copper‑binding peptides and their role in biochemical processes related to cellular communication and structural protein dynamics.
