Afghanistan, Sept. 3 -- Glycyl-L-histidyl-L-lysine copper (GHK-Cu) is a naturally occurring copper-binding tripeptide found in the human body that has attracted growing attention in biomedical research. Scientists are studying GHK-Cu because it may play a role in cellular communication, tissue repair, collagen production and the body's response to oxidative stress. While laboratory studies have produced promising findings, researchers say its medical uses are still being investigated and have not been fully established.
GHK-Cu is made from three amino acids; glycine, histidine and lysine. When these three amino acids bind to a copper ion, they form the GHK-Cu peptide. Researchers have found this peptide naturally in human blood, saliva and...
