Description
This listing supplies GHK-Cu — the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine — as a lyophilized reference material for in-vitro and preclinical laboratory work. Unlike a metal-free peptide, GHK-Cu is a coordinated metallopeptide: the histidine imidazole nitrogen, the terminal glycine amine, and adjacent backbone atoms form a chelation site that holds a single copper(II) ion in a stable but exchangeable configuration. That bound copper gives the solid its characteristic blue tint and defines much of the compound’s chemistry, so laboratories treat it as a copper complex rather than a simple linear tripeptide when planning identity checks, solvent selection, and storage.
The material is intended for researchers characterizing copper-peptide behavior on the bench. It is used as an isolated standalone compound and, in some catalogs, as the copper-peptide component of multi-sequence research blends where matrix-model interactions are studied under controlled conditions. All descriptions below concern the research substance itself — its documented study history, its analytical fingerprint, and standard handling of freeze-dried peptide reference material — and are not statements about outcomes in humans or animals.
