Description
AHK-Cu (Ala-His-Lys Copper Peptide) is a synthetic biomimetic tripeptide that chelates copper ions to form a highly stable copper complex. Structurally analogous to naturally occurring peptides found in human plasma, AHK-Cu has attracted significant attention in cosmetic chemistry research for its potential role in extracellular matrix support, skin barrier function, and cellular signaling pathways.
This listing is for 1 gram of research-grade AHK-Cu powder, supplied for use in laboratory research, cosmetic formulation development, and professional compounding applications.
What Is AHK-Cu?
AHK-Cu is the copper-bound form of the tripeptide Alanine-Histidine-Lysine. Copper peptides in this class are studied for their roles in:
- Collagen and elastin biosynthesis support — Copper is an essential cofactor for lysyl oxidase, an enzyme critical to connective tissue crosslinking
- Antioxidant activity — Copper peptide complexes may upregulate superoxide dismutase (SOD) activity
- Wound healing and tissue remodeling — Research suggests copper peptides support fibroblast proliferation and migration
- Angiogenesis — AHK-Cu has been explored in peer-reviewed literature for its role in stimulating vascular endothelial growth factor (VEGF) expression
- Hair follicle biology — Studied as a potential active in scalp and follicle-support formulations
Suggested Cosmetic Formulation Uses
Cosmetic chemists and formulators commonly incorporate copper peptides into:
- Anti-aging serums and ampoules
- Scalp and hair loss treatment formulations
- Wound-care and post-procedure skincare
- Eye contour and neck firming products
- Bioactive moisturizers and barrier repair creams
Typical usage concentration: 0.001% – 0.05% in finished formulations (adjust based on your own research and stability testing).
Solubility: Water-soluble. Dissolve in distilled or deionized water before adding to emulsions.
Compatibility: Generally stable at pH 5.0–7.0. Avoid combining with strong oxidizers or chelating agents (e.g., EDTA at high concentrations) that may disrupt copper binding.
