A charged tripeptide dissolves where charged things dissolve

Published 24 October 2026 · REVIVE LAB UAE Research Desk · 5 min read
GHK-Cu carries a positive charge on its lysine, a coordinated metal, and polar peptide bonds throughout. It dissolves readily in water and aqueous buffers and poorly in non-polar organic solvents. Its small size helps: there is little hydrophobic surface to resist hydration. Among the compounds in the catalogue it is one of the easiest to dissolve, which is a property, not a recommendation.

Why water

Charged and polar groups are stabilised by water. A tripeptide with a charged side chain, a metal centre and three peptide bonds has polarity throughout and almost no hydrophobic surface. Dissolution is fast and the solution is clear. The copper complex is at least as soluble as the free peptide.

This contrasts with longer, acylated or aromatic-rich peptides that resist dissolving.

Why not organic solvents

Non-polar solvents cannot stabilise charge. Partly polar solvents such as alcohols dissolve some peptides and may dissolve GHK-Cu to a degree, but with risk to the copper coordination. Acetonitrile, used in purification, holds it only as a minor component of a mostly aqueous mobile phase.

Solubility in organic solvent is not a property anyone needs from this compound.

What it implies

Reconstitution chemistry is simple compared with other peptides in the catalogue; analytical sample preparation is straightforward; and the supplied aqueous diluent is chemically compatible. None of this is guidance on volumes or use.
