Zinc carnosine is a proprietary molecular combination of L-carnosine and zinc. When zinc and carnosine are chelated (chemically bound), a new nutrient is formed which has specific properties that are different from those of the two elements taken separately. In 1994, this compound was approved in Japan for the treatment of peptic ulcers. Supported by numerous clinical studies, the arrival of Zinc L carnosine in the nutraceuticals market is attracting considerable attention.
L-Carnosine (beta-alanyl-L-histidine) is a dipeptide of the amino acids beta-alanine and histidine. It is highly concentrated in muscle and brain tissues.
l-Carnosine and carnitine were discovered by Russian chemist V.Gulevich.Researchers in Britain,South Korea,Russiaand other countries have shown that carnosine has a number of antioxidant properties that may be beneficial. Carnosine has been proven to scavenge reactive oxygen species (ROS) as well as alpha-beta unsaturatedaldehydes formed from peroxidation of cell membrane fatty acids during oxidative stress. Carnosine is also a zwitterion, a neutral molecule with a positive and negative end.
Like carnitine, carnosine is composed of the root word carn, meaning flesh, alluding to its prevalence in animal protein. A vegetarian (especially vegan) diet is deficient in adequate carnosine, compared to levels found in a standard diet.
Carnosine can chelate divalent metal ions.
l- Carnosine can increase the Hayflick limit in human fibroblasts,as well as appearing to reduce the telomere shortening rate. Carnosine is also considered as a geroprotector
