Copper Tripeptide CAS 89030-95-5

Copper tripeptide is a complex of copper ions and a tripeptide. Rich in colored copper ions, blue copper peptide exhibits a unique and elegant blue color and was one of the first peptides discovered to have cosmetic benefits. Copper tripeptide has a small molecular weight, making it easier for the skin to absorb. The most significant characteristic of the copper peptide GHK-Cu is its ability to form a complex with Cu ions. This is crucial because many important enzymes in the body and skin require Cu ions, playing roles in connective tissue formation, antioxidant defense, and cellular respiration. Cu ions also function as signaling molecules, influencing cellular behavior and metabolism. Sufficient Cu ions are a signal for stem cell proliferation and tissue repair. GHK also helps reduce the concentration of free Cu ions, preventing oxidative damage.

Copper tripeptide (GHK-Cu) is a bioactive molecule formed by the combination of copper ions and a tripeptide (glycine-histidine-lysine). It possesses properties that promote collagen synthesis, repair skin damage, and have anti-inflammatory and antioxidant effects, making it widely used in anti-aging skincare products, wound repair, and the medical field. Copper peptides activate cell signaling pathways (such as TGF-β) by binding to cell surface receptors, stimulating fibroblasts to secrete collagen, elastin, and glycosaminoglycans, thereby enhancing the skin's supporting structure.

Storage Conditions:

1. Copper tripeptide, as an active polypeptide, is not heat-resistant and should not be exposed to high temperatures for extended periods.

2. Store in a sealed, dry, light-protected, and refrigerated environment. Dissolves at temperatures not exceeding 40°C.

3. When preparing the finished product, pay attention to the pH value of the matrix to avoid excessive acidity or alkalinity, which may affect the activity of the polypeptide.

4. Avoid contact with capryloyl hydroxamic acid and EDTA-2Na, a reagent with strong chelating properties. Precipitation and discoloration are possible.

5. Avoid compatibility with reagents or raw materials with complexing abilities, such as carnosine, glycine, substances containing hydroxide ions or ammonium ions, etc., as these may cause precipitation and discoloration.

Our products are sold well in more than 60 countries and regions including North America, Western Europe, Southeast Asia, Central and South America, etc. We have established long-term and stable cooperative relations with pharmaceutical companies in Europe, the United States, Greece, Germany, Iran, Russia, South Korea, India and other countries.
