GHK-CU

Origin & Classification

GHK-Cu is a copper-binding peptide complex naturally found in human plasma and tissues. The peptide portion consists of three amino acids-glycine, histidine, and lysine-forming a tripeptide that strongly chelates copper ions via the imidazole nitrogen of histidine and the amine groups of glycine and lysine. This molecule falls within the class of endogenous copper transporters and is synthesized for research using solid-phase peptide synthesis followed by copper ion chelation.

Mechanism & Research Context

Research on GHK-Cu focuses on its role in modulating extracellular matrix (ECM) remodeling, wound healing, and inflammation. The complex is known to influence the expression of ECM components such as collagen and decorin, regulate metalloproteinase activity, and interact with integrin-mediated signaling. Investigators examine how GHK-Cu impacts fibroblast proliferation, angiogenesis, and antioxidant responses via pathways involving transforming growth factor-beta, nuclear factor-kappaB, and nitric oxide synthase. Because copper is a critical cofactor for enzymes like lysyl oxidase and superoxide dismutase, the GHK-Cu complex also serves as a model to study trace metal transport and homeostasis in regenerative contexts. Studies aim to delineate mechanistic details of how the peptide-copper complex orchestrates cellular communication within tissue microenvironments.

Composition & Quality

Synthetic GHK-Cu is produced by first synthesizing the tripeptide with purity typically above 95 %, then complexing it with equimolar copper(II) ions under controlled pH conditions. The final product is often supplied as a lyophilized powder or aqueous solution, with rigorous quality control verifying peptide sequence, copper content, purity, and absence of contaminating metals. Production conforms to GMP-aligned standards, and certificates of analysis document all analytical findings. Stability studies ensure that the copper-peptide complex remains intact during storage and handling.
