Carnosine (beta-alanyl-L-histidine) is found exclusively in animal tissues. It is a dipeptide of the amino acids beta-alanine and histidine. Carnosine has the potential to suppress many of the biochemical changes (e.g., protein oxidation, glycation, AGE formation, and cross-linking) that accompany aging and associated pathologies.
L-Carosine is a dipeptide found at millimolar concentration mainly in the brain, muscle and lens of the eye. In model systems it is a potent antioxidant that scavenges oxygen free radicals and transition metal ions. It blocks protein-protein and protein-DNA cross-links induced by hypochlorite anions and toxic aldehydes such as acetaldehyde, formaldehyde, and malondialdehyde, the primary product of lipid peroxidation. It also inhibits nonenzymatic protein glycation induced by aldose and ketose reducing sugars and inhibits the formation of toxic advanced glycation end products (AGE). These activities make it of interest in studies of aging, atherosclerosis, Alzheimer′s disease, and the secondary effects of diabetes.
Dipeptide with potent antioxidant and antiglycation activity; blocks nonenzymatic glycosylation and protein cross-linking induced by reactive aldehydes.
