|Section2= |Section3= }} Copper peptide GHK-Cu is a naturally occurring copper complex of a glycyl-L-histidyl-L-lysine peptide. Since it has three amino acids it is called tripeptide. The GHK-Cu tripeptide has strong affinity for copper(II) and was first isolated from human plasma. It can be found also in saliva and ]. ==Overview== Copper peptides are naturally occurring small protein fragments that have high affinity to copper ions.〔http://www.copper-peptides.com/Science.html〕 In human plasma, the level of GHK-Cu is about 200 µg/ml at age 20. By the age of 60, the level drops to 80 µg/ml. In humans, tripeptide GHK-Cu can promote activation of wound healing, attraction of immune cells, antioxidant and anti-inflammatory effects, stimulation of collagen and glycosaminoglycan synthesis in skin fibroblasts and promotion of blood vessels growth. Recent studies revealed its ability to modulate expression of a large number of human genes, generally reversing gene expression to a healthier state. Synthetic GHK-Cu is used in cosmetics as a reparative and anti-aging ingredient. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Copper peptide GHK-Cu」の詳細全文を読む スポンサード リンク
