Copper Peptide/GHK-Cu CAS 49557-75-7

The copper peptide can also effectively prevent acetylcholine substance nerve conduction, so as to relax muscles, improve the dynamic wrinkles and other effects. Tri-peptide has anti-carbonylation, protects collagen from being damaged by active carbon groups, promotes the growth of type III collagen, and also has anti-oxidation and anti-saccharification effects.



Copper peptide is formed by 3 amino acids (glycosyl-L-histopyl-L-lysine), so it is also called tripeptide or blue copper peptide. Tripeptides consist of three amino acids linked by two peptide bonds to form a ternary molecule. Tri-peptide can play a corresponding role by effectively complexing and transporting copper elements. For example, the complexing copper peptides can effectively stimulate the biogenesis of collagen in fibroblasts, so as to promote the fast healing of wounds. Tripeptides act on cells can increase the vitality and production of collagen cells, so as to improve dynamic wrinkles. So tripeptides are now widely used as cosmetic additives.
