GHK-Cu is one of the most widely studied copper-binding peptides in dermatological and regenerative research. This overview explains what it is and the areas researchers investigate.
What is GHK-Cu?
GHK-Cu (copper tripeptide-1) is a naturally occurring tripeptide made of the amino acids glycine, histidine and lysine, bound to a copper ion. It occurs naturally in human plasma, and its concentration is known to decline with age.
Discovery
GHK was first identified in the 1970s as a factor in human plasma. Researchers later established its strong affinity for copper, forming the GHK-Cu complex that is the subject of most published studies.
Areas of research
In laboratory and in-vitro research, GHK-Cu has been studied in relation to:
- Extracellular-matrix signalling and remodelling
- Collagen and elastin gene expression in human dermal fibroblast models
- Copper transport and delivery
- Antioxidant-related pathways
