Mon - Fri: 9:00AM - 5:00PM 9301 Wilshire Blvd Suite 405, Beverly Hills, CA 90210 Researchers in medicine have spent nearly forty years studying copper peptides (GHK-Cu), also referred to as Cu peptides, which are naturally occurring tripeptides found in human plasma, saliva, and urine
Detailed biophysical studies (X-ray crystallography, EPR, NMR) elucidated that in GHK-Cu, the Cu(II) ion is coordinated by the imidazole side chain nitrogen of histidine, the alpha-amino nitrogen of glycine, and the deprotonated amide nitrogen of the glycine-histidine bond
