Dipeptide-1 is an active peptide with specific physiological functions and is composed of glycine and L-histidine linked by peptide bonds. Glycine is the simplest amino acid with a side chain of only one hydrogen atom. L-histidine, however, carries an imidazolyl side chain, and this structure confers unique chemical properties and biological activity to dipeptide-1.
Basic information:
Chemical name: generally refers to Glycyl-L-histidine.
The molecular formula was C₇H₁₀N₄O₃.
Its molecular weight is 198.18.
Mechanism of action:
Antioxidant function: The histidine residues in dipeptide-1 contain imidazole groups, which can effectively trap free radicals and reduce the damage caused by oxidative stress to cells. In addition, it can regulate the intracellular REDOX balance and activate the activity of antioxidant enzymes, thereby enhancing the antioxidant defense capacity of the body.
Metal ion chelation: the nitrogen and oxygen atoms in its structure can form stable complexes with metal ions, such as binding to copper ions and zinc ions, thereby affecting the metabolism and biological functions of these metal ions in vivo. In skin care, this chelation helps to maintain the balance of metal ions in the skin and improve the physiological state of the skin.
Application areas:
In the cosmetics industry, it is often added to skin care products such as creams, serums and masks due to its antioxidant and skin repair promoting properties. These ingredients are used for anti-wrinkle, whitening and moisturizing, and can effectively improve skin texture and delay the aging process.
Pharmaceutical field: It has shown potential application value in wound healing and tissue repair, and can be used to develop drugs and biomaterials to promote wound healing. In addition, it may also have certain research and application prospects in the treatment of some oxidative stress-related diseases, such as cardiovascular diseases and neurodegenerative diseases.
Food field: It can be added to food as a nutritional supplement, which has certain health effects and helps to improve the antioxidant capacity and immunity of the body.
