Carnosine is a dipeptide compound that functions as a antioxidant in biological systems. It acts by scavenging free radicals and reactive oxygen species, thereby protecting cells and tissues from oxidative damage. Carnosine also plays a role in buffering intracellular pH, helping to maintain the acid-base balance within cells. At the molecular level, carnosine interacts with metal ions, such as copper and zinc, forming stable complexes that can mitigate oxidative stress. Carnosine inhibit the formation of advanced glycation end products (AGEs). Its mechanism of action involves binding to proteins and reducing the formation of these harmful compounds. Carnosine serves as a multifunctional molecule in cellular defense, contributing to the maintenance of cellular homeostasis and protection against oxidative damage.


1. protects epithelial cell membranes in the stomach and restores them to their normal metabolism; 
2. acts as an antioxidant and protects the stomach from alcohol and smoking-induced damage; 
3 has anti-inflammatory properties and moderates production of interleukin-8; 
4. adheres to ulcerations, acts as a barrier between them and stomach acids and helps to heal them; 
5. inhibits activity of Helicobacter pylori bacteria; 
6. does not interfere with the production of prostaglandins essential to the mucosal lining of the stomach; 
7.strengthens these mucosal linings and stimulates production of protective mucous.

L-carnosine is a dipeptide with strong antioxidant and anti saccharification activities, mainly used in cosmetics. It can be used for cell anti-oxidation, maintain body pH balance, and prolong cell life.
