Application:
L-Carnosine (H-Beta-Ala-His-OH; β-Alanyl-L-Histidine) (CAS: 305-84-0) 1). L-Carnosine is a dipeptide of the amino acids beta-alanine and histidine and has the potential to suppress many of the biochemical changes that accompany aging. L-Carnosine is widely applied in food industry, in cosmetics and in medicine field. 2). L-Carnosine has 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. 3). The light transmittance of the turbid human eye lens is enhanced. Antioxidant preparations using carnosine as raw materials can treat senile cataracts. 4). The sensory substance of the olfactory nerve can promote wound healing. It is especially used as an oral medicine for surgical treatment. 5). L-Carnosine has a significant inhibitory effect on lipid oxidation caused by free radicals and metal ions. Carnosine can inhibit fat oxidation and protect meat color during meat processing. Carnosine and phytic acid resist oxidation of beef. Adding 0.9g/kg carnosine to the diet can improve the flesh color and increase the oxidative stability of skeletal muscle, and has a synergistic effect with vitamin E. 6). The use in cosmetics can prevent skin aging and skin whitening. Carnosine can prevent free radicals generated by smoking, and this free radical can damage the skin more than sunlight. Free radicals are the human body. Very active atoms or groups of atoms can oxidize other substances in the human body. Science has proven that peptides can help manage wrinkles in your skin and reverse the signs of aging. 7). The chelate compound of zinc ion and carnosine has been used in Japan for gastritis, gastric ulcers, and dyspepsia symptoms. 8). L-Carnosine has potential antioxidant and anti-glycosylation activity; prevents acetaldehyde-induced non-enzymatic glycosylation and protein coupling. It is also a substrate for carnosine enzyme detection.
